The Connectivity APIs are the telephony control plane for Unpod. They let you bring your own carrier (BYO-SIP), map phone numbers to that carrier, route numbers to your Voice AI agents, and observe the per-number call lifecycle - all over a single REST surface.
Base URL: https://unpod.ai/api/v2/platform/ Every request needs an Authorization: Token <your-api-key> header and an Org-Handle header. See Authentication.

​
The three building blocks

Numbers

Your phone numbers (DIDs). List the pool available to your org and attach a number to an agent so inbound calls reach it.

Trunks

A trunk is your SIP carrier credential. Create one, map numbers to it, and get back the carrier ingress (the origin endpoint).

Calls

Observe the lifecycle: which numbers are linked, to which agent or carrier, and the projection sync state - plus full call logs.

​
How it fits together

1

Inbound Call

Caller dials your DID number → SIP INVITE hits your carrier
2

SIP Carrier

Carrier receives call → routes to your configured trunk endpoint
3

Trunk

Trunk matches incoming DID → bridges to the assigned agent
4

DID/Number

Phone number (E.164 format) → maps to your Voice AI Agent
5

Voice AI Agent

Agent answers → conversation begins
There is one primary termination path:

Key concepts

  • DID/Number - a phone number in E.164 format (e.g. +15551234567).
  • Trunk - a SIP carrier credential (sip_url, transport, port, auth, source-IP allow-list). Secrets are always masked in responses.
  • Origin endpoint - the shared SBC ingress (sip:<host>) the carrier sends inbound calls to, plus the accepted source IPs and mapped DIDs.
  • Bridge - the routing entity numbers attach onto. It is auto-resolved and hidden on the Connectivity surface - you never manage it directly here.
  • Partial success - attach/detach operate on a list; each number reports ok/error independently.
