CPA also passes information to Cisco IOS®.<br>There is a new SIP application type, x-cisco-cpa, for callers to<br>request a CPA operation and for the gateway to relay information to<br>the caller.

(also it looks like it's supported using SIP now...)<br>the requirement is that you need to be doing the signaling from your<br>cisco whatever (presumably CUCM) directly to the terminating gateway.<br>no DSPs are used when you send a call through a CUBE. (and its<br>probably safe to say that forcing it to invoke a transcoder so that<br>there IS a DSP wont work)<br><br>hopefully that sheds some light on why they're trying to get you to<br>use PRIs, but even if you do it that way and can use the FEATURE you<br>are not going not get reliable results over VoIP. Unfortunately it<br>seems liek you need to change your provider or accept that this<br>functionality isnt goign to work properly (or at all)<br>even if you get CUCM/UCCE/UCCX to work by looping PRIs at your<br>gateway, modem and fax tones are likely not going to be transmitted<br>well enough over normal VoIP for this feature to work.<br><br>..you could spend hours making sure modem/fax pas-through works well,<br>but doign that for this purpose is dependant on your providers support<br>and seems silly.<br><br>-Peter<br><br><br><br><br><br><br>On Thu, Nov 29, 2012 at 11:43 AM, Matthew Saskin <msaskin@gmail.com> wrote:<br>> ...and I just read your subject fully.
