Hello all.
I'm rather new. I'm lost and I would really appreciate if someone can
point me in the right direction. I don't know if it something we did
wrong or if it's an issue with our SIP TSP.
We have a new Asterisk 1.4.26 server that has been running without a
hitch for several days.
I have two TSPs connected via SIP and one Linksys SPA-400 with 4 FXO ports.
Calls are arriving correctly via the SPA-400 and one of our carriers.
However, all calls from the other SIP operator are being dropped.
Going through /var/log/messages I see that everything was working
fine until suddenly, in the middle of the night, we started getting
the following error messages on every call that arrived on one SIP trunk.
[Aug 7 00:03:23] WARNING[7310] chan_sip.c: Maximum
retries exceeded on transmission 17BC7D93-81FB11DE-
b87df06a-ee73e...@xxx.yyy.119.39 for seqno 101
(Critical Response) -- See doc/sip-retransmit.txt.

- no reply to our critical packet (see doc/sip-retransmit.txt).
now I just get this (on every call from the faulty trunk)
[Aug 7 17:00:24] WARNING[8308] chan_sip.c: Maximum retries

3f4276ab-829a11de-b7f6898e-f04...@xxx.22.119.35 - no reply to
our critical packet (see doc/sip-retransmit.txt).
I did make a trivial change to the extensions.conf yesterday at 6pm but
the system was taking calls correctly until midnight.
All help is greatly appreciated.
Regards,
Enrique
