Hi,
This is the first time I experience this problem with Asterisk:
all of a sudden SIP registrations stopped working. Active calls kept working
but new calls could not be established (I did NOT perform a "graceful
restart").
Besides, would a "restart gracefully" actually deny SIP registration?
I did not have a network issue because killing asterisk and starting it again
solved the problem.
How can I diagnose what happened to the SIP service (I checked the log but am
quite lost)?
Also, how can I do a simple command-line "check" to see that SIP registrations
are OK? I would like to use a SIP client (like sipsak) to perform a simple
registration from a custom bash script so I can quickly detect if this problem
occurs again and "auto-kill+restart" the asterisk process. I know this sounds
ugly but on my production server, it's better to bring the whole system down
and back up in as little time as possible.
Any suggestions?
Asterisk is 1.2.31.1
Some log lines:
