Hi,

I have a Twilio number +14322397528 connected via SIP
trunking (origination: sip:sip.retellai.com). The number
is imported in Retell as “Custom telephony” with agent
ROYAL PALACE/V12 assigned as inbound agent.

When I call the number, it responds with a different agent
(Advance Medical Psychiatry). The call does not appear in
my Call History.

I also tried TwiML App webhook:

https://api.retellai.com/twilio-webhook/voice/agent_45247e70a1c9df6b6ffad84568

This gives “line busy”.

How can I correctly route inbound calls to agent
ROYAL PALACE/V12?

Thank you.
