London Telecom Consulting helps telecom companies get more from A–Z voice termination, call center traffic and DID numbers: better routes, healthier margins and fewer surprises.
Wholesale voice is a business of thin margins and constant change. Rates move, routes degrade, destinations change their rules, and the details decide whether traffic makes money.
We work alongside telecom companies to review how they buy, sell and run their voice and numbering services, then help them act on what we find. Our work stays deliberately narrow, so the advice you get is specific to your routes, your suppliers and your customers.
Three services at the core of the international wholesale market, and the decisions that make or break them.
Route and rate strategy for international termination to fixed and mobile destinations, so you can compete on price without giving up quality.
Advice for carrying inbound and outbound call center traffic reliably, from capacity planning to keeping ASR, ACD and CLI performance stable.
Guidance on sourcing and managing international DIDs and virtual numbers, covering coverage, suppliers, SIP delivery and billing.
Every engagement follows the same four steps, scaled to the size of the question.
We learn how your traffic, suppliers and customers fit together today, and what you want to change.
We review your rates, routing, quality statistics and contracts to find where value is lost or at risk.
You get clear, prioritised recommendations with the reasoning behind each one.
We stay on hand while your team puts changes in place and checks the results.

We are the controller of the personal data described in this policy. This means we decide how and why it is used, and we are responsible for looking after it under the UK General Data Protection Regulation (“UK GDPR”), the Data Protection Act 2018 and the Privacy and Electronic Communications Regulations 2003 (“PECR”), as amended, including by the Data (Use and Access) Act 2025.

Our website does not use analytics, advertising or tracking cookies. See our cookie policy.
We do not ask for, and ask you not to send us, special category data (such as information about health, ethnicity, religion or political opinions) or information about criminal convictions.
We only use personal data where the law allows us to. The table below sets out what we use it for and the lawful basis we rely on under Article 6 of the UK GDPR.
| Purpose | Lawful basis |
|---|---|
| Replying to your enquiry or quote request and following up on it | Our legitimate interests in responding to business enquiries and developing our business; or taking steps at your request before entering into a contract |
| Providing our consulting services and managing our relationship with clients and suppliers | Performance of a contract with you, or our legitimate interests where the contract is with the organisation you work for |

| Keeping our website and systems secure and preventing spam, fraud and misuse | Our legitimate interests in protecting our business and website |

| Complying with requests from regulators, courts and law enforcement | Compliance with our legal obligations |
Where we rely on legitimate interests, we have considered your rights and expectations and concluded that our interests are not overridden by them. You can ask us for more information about this balancing test.
You do not have to give us your personal data, but if you do not provide the details marked as required on our contact form, we will not be able to reply to your enquiry. We do not make decisions about you based solely on automated processing, including profiling, that produce legal or similarly significant effects.
We never sell your personal data. We share it only with:
Some of our service providers, including our contact form provider and its infrastructure providers, may process personal data outside the United Kingdom. Where personal data is transferred outside the UK, we make sure it is protected as UK data protection law requires: either the destination is covered by UK adequacy regulations (sometimes called a “data bridge”), or appropriate safeguards are in place, such as the International Data Transfer Agreement or the UK Addendum to the EU Standard Contractual Clauses issued under the UK GDPR. You can contact us for more information about the safeguards we use.
We keep personal data only for as long as we need it for the purposes described above, including to meet legal, accounting and reporting requirements.
| Type of data | How long we keep it |
|---|---|
| Enquiries that do not lead to an engagement | Up to 24 months after our last contact |
| Client, contract and correspondence records | For the length of the engagement and then 6 years after it ends, in line with limitation periods for contract claims |
| Invoices and accounting records | At least 6 years from the end of the financial year they relate to, as required by company and tax law |
| Client materials processed on a client’s behalf | As set out in our contract with the client, after which they are deleted or returned |
| Website server logs | For the short period set by our hosting provider, normally no longer than 12 months |
We use appropriate technical and organisational measures to protect personal data against loss, misuse and unauthorised access. These include encrypted (HTTPS) connections to our website and contact form, access controls and passwords on our systems, and limiting access to people who need it. No method of transmission over the internet is completely secure, but if we become aware of a personal data breach we will act on it promptly and notify the Information Commissioner’s Office and affected individuals where the law requires us to.
Under UK data protection law you have the right to:
To use any of these rights, contact us using the details in section 1. There is normally no charge. We may need to ask you for information to confirm your identity. We will respond within one month of receiving your request, which may be extended by up to two further months for complex requests, in which case we will tell you why. When responding to an access request, we will carry out a reasonable and proportionate search.
If you are unhappy with how we have used your personal data, please tell us first so we can try to put it right. You can complain to us electronically through our contact form (choose “Something else” and mention that it is a data protection complaint) or by post to the address in section 1.
We will acknowledge your complaint within 30 days of receiving it, look into it properly, keep you updated, and tell you the outcome without undue delay.
You also have the right to complain to the UK’s data protection regulator, the Information Commissioner’s Office (ICO): ico.org.uk/make-a-complaint, telephone 0303 123 1113. The ICO generally expects you to have raised your complaint with us first.

These terms apply to every consulting engagement between London Telecom Consulting Ltd and its clients. Our services are provided to businesses only. Please read them carefully, in particular clause 3 (our services), clause 6 (fees and payment) and clause 10 (limitation of liability).
1.1 In these terms, the following definitions apply:
1.2 Headings do not affect interpretation. Words such as “including” and “in particular” are illustrative and do not limit the words before them. A reference to “writing” or “written” includes email.
2.1 The Contract is formed when you accept the Proposal in writing or, if earlier, when you instruct us to start work or we start providing the Services at your request.
2.2 These terms apply to the Contract to the exclusion of any other terms, including any terms you seek to impose in a purchase order, confirmation or other document, or that are implied by trade, custom or course of dealing.
2.3 If there is a conflict between the Proposal and these terms, the Proposal prevails, but only for the specific engagement it describes.
2.4 A quote is valid for 30 days from its date unless it says otherwise, and may be withdrawn by us at any time before you accept it.
2.5 You confirm that you enter into the Contract for the purposes of your trade, business or profession and not as a consumer.
3.1 We will provide the Services with the reasonable skill and care of a competent consultant, in accordance with the Proposal and in all material respects.
3.2 We will use reasonable endeavours to meet any dates set out in the Proposal, but they are estimates only and time is not of the essence.
3.3 The Services are advisory. Our recommendations are based on the Client Materials, information available to us and market conditions at the time. Decisions about whether and how to act on them, and the results of those decisions, remain your responsibility. We do not guarantee any particular commercial outcome, such as specific rates, margins, quality statistics, savings or revenue.
3.4 Unless the Proposal expressly states otherwise, the Services do not include: (a) the supply, routing, origination or termination of telecommunications traffic, or the supply of numbers; (b) legal, regulatory, tax, accounting or financial advice; or (c) negotiating or entering into contracts on your behalf. You remain responsible for your own contracts with carriers, suppliers and customers and for complying with all laws, regulations, licences, numbering rules, calling line identification (CLI) rules and sanctions that apply to your business.
3.5 We may make changes to the Services that are needed to comply with applicable law or safety requirements, or that do not materially affect their nature or quality, and will tell you if we do.
4.1 You will: (a) co-operate with us in all matters relating to the Services; (b) provide, in a timely manner, the Client Materials and access to your people, systems and suppliers that we reasonably need; (c) make sure the Client Materials are accurate and complete; and (d) make decisions and give approvals promptly.
4.2 You confirm that you have all rights, licences and consents needed to provide the Client Materials to us and for us to use them to perform the Services, and that our use of them in accordance with the Contract will not infringe the rights of any third party or breach any law.
4.3 If our performance is prevented or delayed by any act or omission by you or your agents, subcontractors or employees (a “Client Default”), we will not be liable for any resulting costs, losses or delay, we may suspend the affected Services until the Client Default is remedied, and you will pay any reasonable costs we incur as a result.
5.1 Either party may request a change to the scope or timing of the Services. No change takes effect until it is agreed in writing, including any change to the Fees, timetable or Deliverables.
6.1 The Fees are set out in the Proposal. Unless the Proposal states a fixed fee, the Fees will be calculated on a time-and-materials basis at the rates set out in the Proposal.
6.2 You will reimburse reasonable expenses we properly incur in providing the Services, such as travel, where they are approved by you in advance.
6.3 All Fees and expenses are exclusive of VAT and any other applicable taxes, which you will pay in addition at the applicable rate.
6.4 Unless the Proposal states otherwise, we will invoice monthly in arrears, and you will pay each invoice in full and in cleared funds within 30 days of the date of the invoice, to the bank account we name.
6.5 If you do not pay any amount by its due date, we may, without limiting our other rights: (a) charge interest and fixed-sum compensation under the Late Payment of Commercial Debts (Interest) Act 1998; and (b) suspend the Services after giving you at least 7 days’ written notice, until payment is made.
6.6 You will pay all amounts due under the Contract in full without any set-off, counterclaim, deduction or withholding, except as required by law.
7.1 Each party will keep the other’s Confidential Information confidential and will not use it except to perform or receive the Services, or disclose it except: (a) to its employees, officers, subcontractors and professional advisers who need to know it for that purpose and are bound by confidentiality obligations no less strict than these; or (b) as required by law, a court, a regulator or a governmental authority.
7.2 Clause 7.1 does not apply to information that is or becomes publicly available other than through a breach of the Contract, that the receiving party already lawfully had, that it receives lawfully from a third party without a duty of confidence, or that it develops independently.
7.3 These obligations continue for 5 years after the Contract ends, or indefinitely for trade secrets.
8.1 We and our licensors keep all Intellectual Property Rights in our methods, tools, templates, know-how and materials that existed before the Contract or are developed independently of it, and in the Deliverables.
8.2 Once you have paid the Fees for them in full, we grant you a non-exclusive, perpetual, royalty-free licence to use, copy and adapt the Deliverables for your internal business purposes. You may share Deliverables with your professional advisers and group companies on a confidential basis, but not otherwise with third parties without our written consent.
8.3 You keep all Intellectual Property Rights in the Client Materials. You grant us a non-exclusive, royalty-free licence to use the Client Materials for the term of the Contract for the purpose of providing the Services.
8.4 Nothing in the Contract prevents us from using general skills, knowledge and experience gained in providing the Services, provided we do not disclose your Confidential Information.
9.1 Both parties will comply with the Data Protection Legislation. Each party is a separate controller of the business contact details of the other party’s personnel, which it will use to manage the Contract. Our privacy policy explains how we handle personal data.
9.2 Where Client Materials contain personal data (such as telephone numbers in call detail records) that we process on your behalf in providing the Services, you are the controller and we are your processor. The subject matter, nature and purpose of the processing is the performance of the Services; its duration is the term of the Contract; and the types of personal data and data subjects are those contained in the Client Materials. You will ensure you have a lawful basis for the processing and have given any notices needed to data subjects.
9.3 When acting as your processor, we will: (a) process the personal data only on your documented instructions, which are the Contract and your reasonable written instructions, unless the law requires otherwise, in which case we will tell you unless the law prohibits it; (b) ensure that people authorised to process it are bound by confidentiality; (c) take appropriate technical and organisational measures to keep it secure; (d) engage sub-processors only with your general written authorisation, which you give by entering into the Contract, telling you of any intended changes so you can object, and imposing on them data protection obligations equivalent to these; (e) not transfer it outside the UK unless the conditions for transfers under the Data Protection Legislation are met; (f) assist you, taking into account the nature of the processing, in responding to requests from data subjects and in meeting your obligations on security, breach notification, data protection impact assessments and consultation with the regulator; (g) notify you without undue delay after becoming aware of a personal data breach; (h) at your choice, delete or return the personal data at the end of the Services, unless the law requires us to keep it; and (i) make available the information reasonably needed to demonstrate our compliance with this clause and allow for and contribute to reasonable audits by you or your auditor on reasonable notice.
Please read this clause carefully.
10.1 Nothing in the Contract limits or excludes our liability for: (a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; or (c) any other liability that cannot be limited or excluded by law.
10.2 Subject to clause 10.1, we will not be liable to you, whether in contract, tort (including negligence), breach of statutory duty or otherwise, for any: (a) loss of profits, revenue, sales or business; (b) loss of anticipated savings; (c) loss of agreements, contracts or business opportunity; (d) loss of or damage to goodwill or reputation; (e) loss or corruption of data or information; or (f) indirect or consequential loss.
10.3 Subject to clause 10.1, we will not be liable for any loss arising from: (a) your decision to implement, or not to implement, any recommendation; (b) the acts or omissions of your carriers, suppliers or customers or any other third party; (c) fraudulent, artificially inflated or unlawful traffic, including toll fraud and international revenue share fraud; or (d) inaccurate or incomplete Client Materials.
10.4 Subject to clause 10.1, our total liability to you arising under or in connection with the Contract, whether in contract, tort (including negligence), breach of statutory duty or otherwise, is limited to the total Fees paid and payable under the Contract in the 12 months immediately before the event giving rise to the claim.
10.5 Except as set out in these terms, all warranties, conditions and other terms implied by statute or common law are, to the fullest extent permitted by law, excluded from the Contract.
10.6 This clause 10 continues to apply after the Contract ends.
11.1 During the Contract and for 12 months after it ends, you will not, without our prior written consent, directly or indirectly solicit or entice away, or employ or engage, any individual who has been employed or engaged by us in providing the Services. This does not prevent you from hiring someone who responds to a general advertisement not targeted at our personnel.
12.1 The Contract continues until the Services are completed, unless terminated earlier under this clause.
12.2 Either party may terminate the Contract by giving the other at least 30 days’ written notice, unless the Proposal states otherwise.
12.3 Either party may terminate the Contract with immediate effect by written notice if the other party: (a) commits a material breach that is irremediable, or is not remedied within 14 days of being notified of it in writing; or (b) becomes insolvent, enters administration, liquidation or any arrangement with its creditors, has a receiver appointed, or stops or threatens to stop carrying on business.
12.4 We may terminate the Contract with immediate effect by written notice if you fail to pay any amount due within 14 days of a written reminder.
12.5 On termination for any reason, you will pay all unpaid invoices and, for Services provided but not yet invoiced, we will submit an invoice that you will pay immediately on receipt. Clauses that are intended to continue after termination, including clauses 6, 7, 8, 9, 10, 11, 14 and 15, will continue in force. Termination does not affect rights and remedies that have accrued by that time.
13.1 Neither party is in breach of the Contract or liable for any delay or failure in performing its obligations (other than payment obligations) caused by events beyond its reasonable control, including acts of God, flood, fire, pandemic, war, terrorism, civil unrest, government action, failure of public utilities or telecommunications networks, or cyber attack. The affected party will notify the other promptly and use reasonable efforts to limit the effects. If such an event continues for more than 60 days, either party may terminate the Contract by written notice.
14.1 Assignment and subcontracting. You may not assign or transfer any of your rights or obligations under the Contract without our prior written consent. We may subcontract any part of the Services, but we remain responsible for the work of our subcontractors.
14.2 Notices. Notices under the Contract must be in writing and sent by email or post to the addresses set out in the Proposal or as otherwise notified. A notice sent by email is treated as received at 9.00 am on the next Business Day after sending; a notice sent by first-class post is treated as received on the second Business Day after posting.
14.3 Entire agreement. The Contract is the entire agreement between the parties about its subject matter and replaces all previous agreements, promises, assurances and understandings. Each party agrees that it has not relied on any statement, representation or warranty not set out in the Contract. Nothing in this clause limits liability for fraud.
14.4 Variation. No variation of the Contract is effective unless it is in writing and agreed by both parties.
14.5 Waiver. A failure or delay in exercising any right or remedy does not waive it, and a single or partial exercise does not prevent its further exercise.
14.6 Severance. If any provision of the Contract is found to be invalid, illegal or unenforceable, it will be treated as modified to the minimum extent needed to make it valid, or, if that is not possible, deleted, without affecting the rest of the Contract.
14.7 Independent contractors. Nothing in the Contract creates a partnership, joint venture or relationship of employer and employee or principal and agent between the parties.
14.8 Third party rights. No one other than a party to the Contract has any right to enforce any of its terms under the Contracts (Rights of Third Parties) Act 1999.
14.9 Anti-bribery. Each party will comply with the Bribery Act 2010 in connection with the Contract.
14.10 Changes to these terms. We may update these terms from time to time. The version in force when the Contract is formed applies to that Contract unless both parties agree otherwise in writing.
15.1 If a dispute arises, the parties will first try to resolve it by referring it to a senior representative of each party, who will meet (in person or remotely) within 15 Business Days to try to settle it in good faith. This does not prevent either party from seeking urgent injunctive or other interim relief.
15.2 The Contract, and any dispute or claim (including non-contractual disputes or claims) arising out of or in connection with it or its subject matter or formation, is governed by and construed in accordance with the law of England and Wales.
15.3 Each party irrevocably agrees that the courts of England and Wales have exclusive jurisdiction to settle any dispute or claim (including non-contractual disputes or claims) arising out of or in connection with the Contract or its subject matter or formation.
