I'm trying to solve a problem with peers unreachable.
I extracts a tcpdump of one peer and when the peers become unreachable I see that every time the Asterisk send OPTIONS and the peers reply 200 OK. But when the peers become unreachable, happens a break in which the Asterisk does not send OPTIONS. However I was running a ping in IP address from computer where the peer is logged and the server communicates with the host normally.
It's a problem with the Asterisk that does not sending OPTIONS sometimes?
The Asterisk version is: Asterisk 11.20.0 built by root @ rmtelecompbx on a x86_64 running Linux on 2015-10-17 21:02:16 UTC.
This is session general in the Asterisk sip.conf:
callcounter = yes
language=pt_BR ; Default language setting for all users/peers
useragent=TotalIPPBX ; Allows you to change the user agent string
registerattempts=10 ; Number of registration attempts before we give up
constantssrc=yes ; Don't change the RTP SSRC when our media stream changes
Can someone help me?
