Hello,  
I’m using a custom SIP integration (Zadarma → Retell).  
Even though I have **only one agent** configured and assigned to the phone number, inbound SIP calls are still being routed to an **old Real Estate demo agent** that no longer exists in my account.

Please **reset the inbound SIP routing / fallback agent** for my phone number **+34951870243** and rebind it to my current agent.

This seems to be a cached SIP routing issue.

Hi Omar,

The phone number has always been in the SAME Retell account.  
It was never moved to another Retell account.

Old agents were created and later deleted within the same account.  
Currently there is only ONE agent in the account.

My Org ID is: org\_GlEAYZwYlRHgLWef

Thanks.
