Any issues with incoming SIP to LiveKit Cloud? Are SIP calls to LiveKit Cloud agent are getting rejected.

We have the same issue. We are a telco, connecting our customers to Retell.AI via SIP Elastic trunking. This setup has been working for many months and processing several hundred calls per day. Failures on inbound calls started appearing gradually at December 5th 20:42 UTC , with initially few calls getting rejected, and then all calls rejected at 21:30 UTC.

wow. is it

sngrep

?

I have same issue yeserday and today

I got a lengthy debug session with Retell, apparently there was some change that broke accepting numbers in E.164 format. The quick solution now is to add the same number with +

This does not sound right to me. Months ago you had to make sure to have the

+

or no plus based on the inbound dialed numbers. But that is no longer the case. Numbers should work if you have the

+

or not. What problem did you have?

We were always sending numbers in E.164 without

+

. Then last Friday they stopped coming to Retell. Today when I added the same number with

+

on their dashboard, it started working. And it keeps working even if I don't send

+

in call. So, somebody messed up normalizing

ok, that must be something on the retell side. I had a look at the call id you shared and it was routed to a room as expected.

Seems so. Thanks for the assistance
