I need to find the "Call-ID" of an outgoing leg.
If I call the following code, which is correct according to the manual:    
   # at some point in my code I place an outoing call    
   leg setup $my_destination callInfo leg_incoming     
   # later in the code, I need to retrieve call-id to match cdrs with a vendor    
   set call_id [infotag get leg_proto_headers "Call-ID" leg_outgoing]
error:  
   expected integer but got "leg_outgoing"CallID leg_outgoing was not an Incoming Leg  
 
what am I doing wrong?   thank you

Yaw-Ming,
 
 thanks for your help. A couple of questions:
1.- Isn't the ev_setup_indication event only called for incoming calls? If so, I won't be able to get the outgoing call-id.
 
2.- I don't see any references to "set callid" in the programming guide.
 
thanks again

Yaw-Ming,
 
 using 
  'set callinfo(newguid) "true"'
solved our problems! Thanks for your help!
