[VoiceOps] SIP options "ping"

[Steve Teti]

I'm trying to find a way to monitor the status of the SIP service on 
some Asterisk servers.  I had a situation the other day where the daemon 
was running, but hung, and would not respond to requests.  ICMP pings to 
the machine worked, as did monitoring of the process list, but the 
machine would not respond to SIP requests.  I found this draft during my 
research:

http://tools.ietf.org/html/draft-jones-sip-options-ping-02

Anyone know of a unix utility that can easily send a SIP OPTIONS request 
to a remote server and return the results in a useful format?  I could 
probably construct one using Net::SIP in perl, but I like to take the 
easy way out when possible :).

Thanks,
Steve
