Unable to call a connected peer

[ast8864]

Hello everyone,
First of all, thanks in advance for your support. I am pretty new in Asterisk.
I am running asterisk on Debian 10. These are the connected peers:

Name/username Host Dyn Forcerport Comedia ACL Port Status
1001/1001 10.84.30.1 D Auto (No) No 5060 OK (4 ms)
1201/1201 10.84.30.100 D Auto (No) No 5060 OK (17 ms)

When trying to call from 1201 to 1001 the following error appear in the CLI:

== Using SIP RTP CoS mark 5

I don’t know where the IP 88.1.190.174 comes from.
Any idea why it is not working??

In that case you should not be using chan_sip, as it is being retired.

Debian 10

To use Asterisk on Debian you need to compile from source. The package on bullseye is based on a past end of life version, and there is no package on bookworm.

Received AVPF profile

AVPF is normally associated with WebRTC, which is not something you should be using until you are familiar with debugging VoIP networks.

I don’t know where the IP 88.1.190.174 comes from.

It presumably comes from the incoming SDP. Looks like you have a misconfigured NAT environment.

That’s before you even try to make an outbound call.

You have multiple problems and a deprecated channel driver. Debugging would require detailed information on your network and also a protocol trace (sip set debug on).
