Today I have had a new Nagios plug-in I’ve been working on published. The plug-in is check_asterisk_ami and is capable of checking asterisk VOIP server for number of active calls/channels and also the number of SIP & IAX Peers in use.
The plug-in can be found here:

I already have a few people using this with success, Inspiration for this plug-in came from our asterisk system being hacked and calls routed through our server; fortunately I managed to catch it before it got too bad, and this is now on 24hour SMS support.
