I am getting following warning very frequently on Asterisk 18 [Aug 17 15:01:26] WARNING[8722][C-00000337]: chan_sip.c:8153 sip_indicate: Don’t know how to indicate condition 36

That would be stream support related, which is not supported in chan_sip and can be ignored.

You can ignore it. If there’s actually a problem, then you should state what the problem is. A warning message that can be ignored isn’t a problem itself.

That warning message is completely unrelated to SIP trunks going unreachable. Going unreachable occurs when chan_sip sends a SIP OPTIONS and gets no response. You would need to examine the network traffic, such as through a packet capture or “sip set debug on” and see if a SIP response is occurring. …

I am Dialing One server from Other using SIP, should I use some other mechanism like IAX2

SIP or IAX2 works for connecting Asterisk instances.

What should I do, Very frequently all servers gets unreachable, then We need to restart Asterisk to proceed, It is a Major Issue, Please help

I’ve told you what has to be done: “You would need to examine the network traffic, such as through a packet capture or “sip set debug on” and see if a SIP response is occurring.” It’s also possible that chan_sip itself has a problem, and as I stated that would not get looked into.
