[asterisk-users] asterisk SIP, SIPAddHeader() and Cisco GED-125

[David Backeberg]

Greetings:

I'm in the situation where I'm trying to splash information picked off
by an asterisk IVR into a Cisco call center environment. I'm under the
impression that the ONLY way to do this is to setup socket connections
with the Cisco "voice processor", or CVP, and send packets
corresponding to GED-125. Cisco has a detailed 100+-page document
detailing the internals of what these packets need to look like.

But wouldn't it be nice if instead, you could use SIPAddHeader() with
X tags and have Cisco pick off the out-of-band values from SIP
packets? Wouldn't it be even nicer if there was a middleware that
spoke GED-125 out of one side, and spoke SIP X headers on the other
side?

I will soon be able to tell you about the bowels of this interaction,
but before I go down this road, does anybody want to speak up with
lessons learned from doing this themselves? I'm assuming I'm going to
end up creating a library in Perl to help me do this (that is, the
out-of-band conversation with the CVP).
