Subject: Inbound caller ID missing for retell-twilio number +1 (762) 300-6704
Hi Retell team,
We are using a managed Retell-Twilio number:
phone_number: +17623006704
phone_number_type: retell-twilio
inbound_agent_id: agent_03de4d3e210064b5104610bed7 (Daniel Inbound Agent v177)
For 100% of inbound calls, the webhook payload shows:
"from_number": "+"
Full example:
{
"event": "call_started",
"call": {
"call_id": "call_206fdb85bf56541df4fff2ca5b7",
"call_type": "phone_call",
"agent_id": "agent_03de4d3e210064b5104610bed7",
"agent_version": 177,
"from_number": "+",
"to_number": "+17623006704",
"direction": "inbound",
"telephony_identifier": {
"twilio_call_sid": "CA089e8bf88a6c71ec6a7fc583d612ad85"
},
"custom_sip_headers": {
"x-twilio-accountsid": "ACb52c6e2497a850eb6280179b8192d22a",
"x-twilio-callsid": "CA089e8bf88a6c71ec6a7fc583d612ad85"
}
}
}
And the phone number API shows:
{
"phone_number": "+17623006704",
"phone_number_type": "retell-twilio",
"sip_outbound_trunk_config": {
"termination_uri": "acb52c6e2497a850eb6280179b8192d22a.retell.pstn.umatilla.twilio.com",
"transport": "TCP"
}
}
There is no telephony / caller ID configuration exposed in the new dashboard or via API.
Can you please:
1) Confirm whether inbound caller ID is supported for
phone_number_type = "retell-twilio"
in my workspace.
2) If yes, enable full caller ID passthrough for this number (Twilio From / P-Asserted-Identity → call.from_number).
3) If not supported yet, let us know the ETA or recommended workaround that does NOT require us to bring our own Twilio number.
Right now we can only see
"+"
for all inbound calls and cannot identify callers.
Thanks!
