[asterisk-users] how to check Asterisk SIP registration

[Danny Nicholas]

"Sip show users" or "sip show peers" should do the trick, but I'm not sure
about 1.2;  all of my experience is in the 1.4 branch.

Subject: [asterisk-users] how to check Asterisk SIP registration

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:
