I am using the Asterisk 16 Version on my centos servers. I have the SIP trunk from telecom operator(No Firewall between Server and Telecom SBC), SIP extension registerd on IP Phone, and LoopBack SIP trunk(127.0.0.1) on servers.
I have noticed that all of the SIP Peers are going unreachable (Including Loopback IP peers and telecom SIP) and getting reachable after 3-4 Minutes.
Can anyone help to understand the issue? Is this something my asterisk SIP is getting hang?
