RE: [Asterisk-Dev] Asterisk Manager and app_dial challenge.

[Zac Wolfe]

That's exactly the issue I ran into while working on Jasterisk. My solution was to modify pbx.ast_request to take an additional optional parameter that could act as a call identifier and set a predefined variable in the newly created channel to that variable.  Then, when I receive a "newchannel" or "newstate" event, I can find the channel and check to see if it's already associated with a "call" object.  Or, I suppose you could modify the event to include a "Call_UID" field so you wouldn't have to grab the variable from the channel directly (hey why didn't I do that?).   Zac -----Original Message----- From: Brian Roy [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 12, 2004 1:43 PM To: [EMAIL PROTECTED] Subject: [Asterisk-Dev] Asterisk Manager and app_dial challenge. All,   Any suggestions you might have would be appreciated.   I have written a pre-alpha Call Data Server in Java for Asterisk. It is designed to provide similar functionality to circuit switch CTI solutions (like Genesys) including maintaining call state, extension state, and most importantly – carry user specified data elements with the call for Screen Pop. The challenge I have run into is with the functionality of the Dial command and the Link, Unlink, Ring and Ringing events.   In order to properly perform screen pop, ideally the event Ringing on the target (or all targets) extension rings. The challenge is that there is no linkage between the new calls ringing the target extensions and the original inbound call that has the call data associated. Not until the target extension answers and the LINK event is fired can those two calls be associated.   I have reviewed the code for both pbx.c and app_dial.c and can find no way to modify the code to accomplish it. Ideally, I would like a new event “PRELINK” which, when the Dial command is fired is set to the manager with the same format as a LINK event:   Line: 0: Event: Link Line: 1: Channel1: SIP/147.135.0.129-0816e408 Line: 2: Channel2: SIP/4403-2871 Line: 3: Uniqueid1: 1097608761.39 Line: 4: Uniqueid2: 1097608761.40 Line: 9:   The PRELINK should be fired once for each target of the Dial Command allowing “pop” for all of those clients.   Thoughts?   Brian Roy [EMAIL PROTECTED]
