[asterisk-users] how to lookup a call

[Jerry Geis]

I am using 1.4.43 currently.

I am using the AMI to originate a call over a SIP Trunk to my cell 
XXX506YYYY. works fine.
when the call is active I do a "core show channels concise" and I get:

SIP/testsystem-00000ad0!smvoice-dialout!callprogress!4!Up!AGI!smvoice!0!!3!24!(None)

My AGI is called smvoice.
No place does my number show up.
How do I "lookup" my call so I can "hangup" the call at a later time.

In my case there my be more than one call active at a time, and I want to
hangup the correct call. I know I need the data "testsystem-00000ad0" to 
cancel my call
but how do I "associate" that with my number so I can find the right 
call to hangup.

Thanks,

Jerry
