​
Bind Voice Agents

Only when you bind agents to a number will the number be able to receive and make calls.
  • You can assign different inbound and outbound agents to the same number.
  • Leave an agent unset to disable inbound or outbound (e.g. if you’re doing outbound only and don’t want callbacks, leave inbound_agent_id unset).
  • After binding an inbound agent, your number is ready to receive calls immediately.

​
A/B Testing

See A/B Testing to route a percentage of inbound calls to different agents.

​
Inbound Call Webhook

Often you’ll want to use different agents to handle inbound calls on the same number, provide dynamic variables, or customize other call fields per-call. Use the Inbound Call Webhook to handle this.
Read more at the Inbound Call Webhook documentation.

​
Inbound Custom SIP Headers

You can use custom SIP headers to pre-set dynamic variables for a call. UponAI extracts any header starting with sip.h.x-, along with common SIP headers like Diversion, History-Info, User-To-User, and P-Asserted-Identity, and converts each into a dynamic variable by stripping the sip.h. prefix. Examples:
  • sip.h.x-caller: abc → x-caller: abc
  • sip.h.p-asserted-identity: +12345678910 → p-asserted-identity: +12345678910
  • sip.h.diversion: <sip:2000@192.168.254.254>;privacy=off;reason=no-answer → diversion: <sip:2000@192.168.254.254>;privacy=off;reason=no-answer

Get Call Details

After a call completes, you can retrieve full call information:

API

Use the Get Call API to retrieve the transcript, recording, latency tracking, and more.

Webhook

Set up webhooks to receive real-time updates when a call is initiated, ends, and is analyzed. Read more at the Call Webhook Guide.
