In PCAP it could look like this:
The reason is Local IP in the Contact header:
INVITE sip:---@143.0.*.* SIP/2.0 Via: SIP/2.0/UDP 10.77.252.155:5060;branch=z9hG4bK0cf0cdad Max-Forwards: 70 From: "75201" <sip:75201@10.77.252.155>;tag=as4be522cb To: <sip:519975---@143.0.*.*> Contact: <sip:75201@10.77.252.155:5060> Call-ID: 29b0f9fc2055cbc86fff11c42503bb58@10.77.252.155:5060 CSeq: 102 INVITE User-Agent: Asterisk PBX certified/11.6-cert15 Date: Tue, 19 Jan 2021 22:34:45 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH Supported: replaces, timer Content-Type: application/sdp Content-Length: 301
Here is the problem: Contact: <sip:75201@10.77.252.155:5060>
In this case, we see: User-Agent: Asterisk PBX certified/11.6-cert15
So we can suggest fixing externip in /etc/asterisk/sip.conf to properly set External IP on the Asterisk under NAT.
With different Switches, solution is the same, but the way to achieve it will differ.
