[asterisk-users] Extensions fail to register themselves when all trunks are unreachable.

[Francesco Namuri]

Hi,
my asterisk server has a strange behavior when all trunks are
unreachable (for example due to internet connection), it doesn't accept
registrations from any internal extension, and, obviously, I can't do
any internal call.

On the log I see only lines like:

[2013-09-30 01:35:04] NOTICE[1827] chan_sip.c: Peer 'xxx' is now
UNREACHABLE!  Last qualify: 36

and then

[2013-09-30 01:35:07] NOTICE[1827] chan_sip.c: Peer 'yyy' is now
Reachable. (36ms / 2000ms)

How can I troubleshot this issue?

Thank you very much in advance.
