Why peer gets unreachable short time?(stays reachable around 30 second or 1 minute than debug log says it is unreachable) Peer is same local network with asterisk. But i try to test TLS. It can be about TLS?
Not sure if is the TLS , But I was reading on this forum about a bug that make sip peers unrechable I will try to look for the info , and if I find it, I will pass it to you. Anyway my sugestion is :test without the LTS and verify if the same problem happen
Phone-A: This ip phone is in public field and under the nat.(Only one router)(forexample public ip: 184.108.40.206),
Phone-B: This ip phone is same local network with asterisk and under the 2 natted routers.( public ip: 220.127.116.11)
when i call from Phone-A to Phone-B so it is not working. But When i call from Phone-B to Phone-A so it is working.
If i exchange the Phone network locations so in both direction is working!!!(I mean, Phone-A is located to Phone-B’s network location, and Phone-B was located to Phone-A’s network location)
When i typed, sip show peer Phone-A and sip show peer Phone-B so there is only one differences. Difference is only “TLS” word. One of them writing like “tls”, in another one write like “TLS”
Output of the sip show xxx

Problem is about phone software implementation?
