Depends on which signaling technology is in use.
I'll assume SIP here.
Checking whether it's processing calls (especially in some sort of
subjective way) can be a bit hard. But checking if the SIP interface
on it is responsive is quite easy; just install a tool called SIP
Swiss Army Knife ('sipsak'):
sipsak -T -s sip:[email protected]
sa...@octavia:~$ sipsak -T -s sip:[email protected]
warning: IP extract from warning activated to be more informational
0: ?? (70.357 ms) SIP/2.0 404 Not Found
without Contact header
Conversely, if it were down:
sa...@octavia:~$ sipsak -T -s sip:[email protected]
warning: IP extract from warning activated to be more informational
send failure: Connection refused
Or it would just time out.
This command returns a value which can be captured by a shell script,
and so it is possible to build it into something like a Nagios plugin,
for example.
