Some error about sip

[tricksterANDthug]

Hello, I have set up the corresponding services on an AWS EC2 server, including LiveKit server, LiveKit SIP, and Voice Agent. After testing, calls from China can be successfully connected, but calls from the U.S. cannot. Could you please confirm if there are any restrictions on U.S. calls with STIR/SHAKEN ratings of A, B, or C?

there are no restrictions from our side.

@tricksterANDthug you may notice the "reason": "media-timeout" in the logs. This indicates that LiveKit SIP received no media packets from remote server. This usually means that there's a firewall issue. Please make sure all media ports are open (by default: 10000-20000, UDP).
