I believe that adding qualify=<enter your value in seconds here> to your 
trunk configuration is what you are looking for for the monitoring 
state.  This will send SIP OPTIONS packets to the trunk periodically.  
See "qualify" in the sip.conf samples or documentation.

 From there you can use a monitoring solution to monitor the state of 
the trunk.  Alternatively you can use a OSS tool called SIPp to test SIP 
devices.  See *http://sipp*.sourceforge.net for more information.  This 
is an indispensable tool for SIP and Asterisk troubleshooting.

I hope this helps.
