Numbers for AI Voice Agents
Phone numbers and SIP trunks for AI voice agents
AI voice agents need two things to make and take real phone calls: a phone number and a SIP route to the phone network. We supply both, so an agent on a platform that accepts external SIP trunks or imported numbers can answer on a local number in the markets it serves.
At a glance
Give your AI agent a real phone number in 100+ countries, delivered over SIP to AI platforms that accept one, with no lock-in.

Features
How your agent connects
IP-allowlist interconnect
We authorise your agent platform or SBC by its IP address, with no registration needed.
Registered SIP credentials
Or register a trunk with a username and password, for platforms that authenticate by SIP digest.
Inbound & outbound
Your number brings calls in to the agent, and the agent calls out over the same trunk with your chosen caller ID.
Use cases
What businesses use it for
AI receptionists
Answer inbound calls on a local number and let the agent handle routine questions.

Changing platforms
Keep your number when you move to a different AI platform by re-pointing it to the new SIP address.
