I have also tried this:

set testa [infotag get leg_proto_headers leg_incoming]
puts "\n\n\ntesta=$testa\n\n"
set testb [infotag get evt_proto_headers]
puts "\n\n\ntesta=$testb\n\n"


but these both came back with an empty string:

Aug 4 17:48:22.871: //4551//TCL :/tcl_InfotagGetObjCmd: infotag get leg_proto_headers leg_incoming

and according to the documentation, if I do not specify an attribute in the infotag get command, all attributes are supposed to be returned in a single string seperated by the "&" character.

I asked this question in 2003 and they told me it would be a lot of work and that I needed to make a business case. Because of this I have to filter all IP-IVR to G729. in rare situations where G723 is needed I use an prefix to select a different dial-peer which pulls different files.

this is much like the question of asking to be able to select a target IP from within TCL. Again ¿provide a business case¿. unless a large company like ATT or Bank of America wants something it won¿t become a new feature. Thinking like this is very short sighted.

Subject: New Message from WESLEY PHILLIPS in Voice Gateway API (VGAPI) - TCL-API: codec detection

WESLEY PHILLIPS has created a new message in the forum "TCL-API":

--------------------------------------------------------------
Is there a way to identify the codec that was negotiated for the leg_incoming leg? I am having a problem getting a prompt to play out on the inbound leg because of codec mismatches. I would like to be able to pull the codec for the inbound leg from an infotag, and then do either a switch or if/else statement to point a media play command to different files based on codec.

Thanks
Wes
