Summary:                    chan_sip.c: Peer 'XXX' is now UNREACHABLE
Description: 
Hello,

I work with asterisk 1.6.1.18 (from fedora packages) behind a nat and
hardphones (linksys SPA922-942 and siemens C470IP) which are behind
different nats too. For testing, I also have a SPA942 on my LAN. Moreover,
public IP are dynamic (because our unique ISP does not provide fixed IP
addresses) but this is not the purpose for that issue because all worked
very well for months.

Since several days, I have "unreachable" messages on the CLI that should
not be due to NAT timeouts because I also have them with my LAN peer.
Nothing has changed on my server and the problem appeared suddenly. For
information, the problem occured twice this year with earlier asterisk
versions and I don't know what resolved it.

Of course, during the time the peer is unreachable, it cannot be called
which is a problem.

This time, I have debug information. Here are my confs & logs.

Regards

Hello,

If you check the debug file in attachment, you will find some messages
like:

chan_sip.c: SIP TIMER: Not rescheduling id #...:OPTIONS (Method 3) (No
timer T1)

It appears that if the server does not receive a reply from the device,
the timer T1 seems not being defined (it should be set to the round-trip
time from the server to the peer)

Do you still think it is not a bug ?

Regards
