Version 2026-11-06 · Effective 2026-11-06

1. How to use this page

This page sets out additional requirements that apply when you use sip.io services in, or to reach, particular countries. It forms part of the Terms of Service and supplements the Acceptable Use Policy, Voice Policy, Messaging Policy, Phone Number Terms and Emergency Services pages.

Telecommunications rules vary widely and change often. This page is a summary to help you plan; it is not legal advice and is not a complete statement of the law. You are responsible for knowing and complying with the laws that apply to your use of the Services, including in every country where you originate or terminate traffic, hold numbers or have end users. Country-specific points below are general guidance; confirm the current rules with local counsel before launching in a country.

2. General requirements (all countries)

  • Identity and address. Many regulators require that phone numbers be assigned only to identified end users with a local address. Provide accurate KYC information and keep it current. We may suspend or reclaim numbers if documentation is missing, false or expired.
  • Caller ID. Present only caller ID you own, have been assigned, or are authorised to use. Do not spoof or obscure caller ID to mislead.
  • Consent and recording. Obtain consents required for recording, transcription and AI processing. See Call Recording and AI Services Terms.
  • Marketing. Comply with telemarketing, do-not-call and anti-spam rules in the recipient’s country.
  • Emergency calling. Our Services are not a replacement for a traditional phone line unless expressly stated. Read Emergency Services.
  • Lawful use. Do not use the Services to bypass local termination rules, licensing regimes or sanctions.

3. Requirements by service

3.1 Voice

  • Configure valid caller ID on every outbound call; we may block or rewrite calls with invalid or unauthorised caller ID.
  • Respect calling-hour restrictions and do-not-call lists where required.
  • Auto dialler campaigns must meet abandonment-rate, identification and opt-out rules in the destination country.
  • Some destinations prohibit the use of internet-based routes to terminate calls to local numbers (see India, section 4.12).

3.2 Phone numbers

  • Numbers remain subject to the rules of the national numbering authority. Number types (geographic, national, mobile, toll-free) may have usage restrictions, such as local presence for geographic numbers.
  • Porting in and out follows national porting rules and timelines.
  • We source numbers through our wholesale provider; additional documentation may be required at any time by that provider or the regulator. See Phone Number Terms.

3.3 Messaging

  • Application-to-person messaging is subject to registration in several countries (for example 10DLC and toll-free verification in the United States, sender ID registration in many others).
  • Opt-in, opt-out and content rules apply. See Messaging Policy.
  • WhatsApp Business messaging is additionally subject to Meta’s WhatsApp Business policies.

3.4 BYOC

  • When you bring your own carrier, you remain responsible for that carrier’s regulatory obligations, including number registration, emergency calling, STIR/SHAKEN attestation and lawful interception, unless we expressly agree otherwise. See BYOC Terms.

3.5 Emergency calling

  • Where emergency calling is offered, you must register an accurate emergency address for each number or device, update it when the user moves, and inform users of limitations. Nomadic and webphone use may limit our ability to route emergency calls to the right answering point.

4. Requirements by country or region

4.1 United States

  • E911. Interconnected VoIP providers must provide Enhanced 911 service, obtain a registered location from each customer before activation, offer a way to update it, and give customers notice of E911 limitations, which customers must acknowledge (47 C.F.R. Part 9). Customers must distribute warning labels and notices to their users where required.
  • Kari’s Law. Multi-line telephone systems (MLTS) must allow users to dial 911 directly without a prefix (such as “9”) and must notify a central location (such as a front desk or security) when 911 is called. Customers that configure PBX dial plans or IVRs on sip.io are responsible for meeting these obligations for systems they manage.
  • RAY BAUM’S Act. 911 calls from MLTS and fixed and non-fixed VoIP must convey a “dispatchable location” (street address plus floor, room or suite where needed) with the call. For non-fixed devices, an automated or user-provided updated location is required.
  • TCPA. The Telephone Consumer Protection Act and the FCC’s rules restrict autodialled and prerecorded or artificial-voice calls and texts, including AI-generated voices, without prior express consent (prior express written consent for telemarketing), and require compliance with the National Do Not Call Registry, calling-time limits and caller identification. State “mini-TCPA” laws may impose additional rules.
  • STIR/SHAKEN. Calls are signed with STIR/SHAKEN attestation where we are the originating provider and have authority to do so. Customers must only use numbers they are authorised to use to obtain full attestation. Calls arriving through BYOC trunks may be signed by your carrier.
  • Robocall Mitigation Database. Voice service providers, including intermediate and gateway providers, must file in the FCC’s Robocall Mitigation Database. Customers that are themselves voice service providers (for example resellers or wholesale customers) must maintain their own filing and provide the filing to us on request; we may refuse traffic from providers not listed.
  • Traceback. Customers must respond to traceback requests from the USTelecom Industry Traceback Group within the timelines required by FCC rules. See Report Abuse.
  • 10DLC. A2P SMS/MMS from US local numbers requires brand and campaign registration through The Campaign Registry. Unregistered traffic may be blocked or surcharged by carriers. Toll-free messaging requires toll-free verification.
  • CPNI. See our CPNI Policy.
  • Taxes and fees. Federal Universal Service Fund and state and local 911 fees and taxes may apply.

4.2 Canada

  • 9-1-1 / NG9-1-1. Fixed and nomadic VoIP services must provide 9-1-1 access with a registered address, and customers must be informed of limitations. Canada is transitioning to Next Generation 9-1-1 under CRTC decisions.
  • Unsolicited Telecommunications Rules. Telemarketing calls must comply with the CRTC’s National Do Not Call List, telemarketing rules and automatic dialing-announcing device (ADAD) rules, including registration with the National DNCL operator and identification requirements.
  • CASL. Commercial electronic messages, including SMS, require consent, sender identification and a working unsubscribe mechanism under Canada’s Anti-Spam Legislation.
  • STIR/SHAKEN. The CRTC requires STIR/SHAKEN for IP-based voice calls.

4.3 European Union

  • EECC. The European Electronic Communications Code (Directive (EU) 2018/1972), as implemented by each member state, requires contract transparency, summary information and access to emergency services (112) for number-based interpersonal communications services, including caller location where technically feasible.
  • ePrivacy. The ePrivacy Directive (2002/58/EC) and national laws govern confidentiality of communications, traffic and location data, unsolicited marketing (generally opt-in for automated calls and electronic messages to individuals) and calling line identification.
  • National number KYC. Most member states require proof of identity and an address in the relevant numbering area or country for geographic numbers, and some for national and mobile numbers. Requirements differ by country and number type.
  • GDPR. See our Privacy Policy and Data Processing Addendum.

4.4 United Kingdom

  • Ofcom General Conditions. Providers must comply with Ofcom’s General Conditions of Entitlement, including access to emergency services on 999 and 112 with caller location information (GC A3), and calling line identification requirements (GC C6), which require valid, dialable caller ID that identifies the caller and prohibit presenting numbers the caller is not authorised to use.
  • CLI rules. Ofcom’s CLI guidance requires blocking of calls from abroad presenting UK CLIs where not legitimate, and providers must not allow CLI spoofing. Customers must use CLIs they are authorised to present.
  • Number usage. Numbers must be used in accordance with the National Telephone Numbering Plan; certain ranges have usage restrictions.
  • Marketing. The Privacy and Electronic Communications Regulations (PECR) and the Telephone Preference Service govern marketing calls and texts.

4.5 Israel

  • Communications Law. Telecommunications services are governed by the Communications (Telecommunications and Broadcasting) Law, 5742-1982 and licences issued by the Ministry of Communications. Providing certain services to the public in Israel requires a licence.
  • Number KYC. Israeli numbers may be assigned only to identified subscribers in accordance with Ministry of Communications rules, with identity documentation retained.
  • Amendment 40 anti-spam. Section 30A of the Communications Law (Amendment 40) prohibits sending advertising by automated dialling systems, SMS, fax or email without the recipient’s prior express consent, with limited exceptions, and requires sender identification and an easy refusal mechanism. Statutory damages may apply.
  • Emergency calling. Access to emergency numbers (such as 100, 101 and 102) is subject to Ministry of Communications requirements.
  • Privacy. See the Israel section of our Privacy Policy.
