I have a trunk IAX that is host=name.dyndns.org and when he change the IP every morning the resolved name for name.dyndns.org does not get update so the result is Status UNKNOWN in the Asterisk (Ver. 11.5.1): Peers IAX2
I have System Admin DNS 127.0.0.1 192.168.0.1 and 8.8.8.8
In SIP setup SRV lookup enables
Did the same thing in IAX settings
Start with pinging that URL from a system shell and see if the system knows the right IP. Then we can move on to figuring out why Asterisk is not doing what it is supposed to do.
I check this morning and the IP of the distant PBX have change and the IAX2 Peers is 184.175.15.188 (S) 255.255.255.255 4569 UNREACHABLE
If I ping on a root session I have the new IP
I reload the PBX and now the new IP is there Status OK (36 ms)
