[Serusers] Monitoring tool

[Tomas Björklund]

Hi all,

What software do you use for making sure that your sipserver(s) are online 
and working?

I'm on the lookout for something that I can use with Nagios (ie anything 
that I can run from a shellprompt).

I have tried sipsak but it's not working on solaris (some strange 
bind/socket operations that breaks the program)

I would like the same feature as sipsak has,

1. Register account
2. Call account
3. Check for invite

Doing an external call to a free number would also be nice, just wait for 
the 200 OK and then cancel the call.

Best regards,

Thomas Björklund
