OCSG integration with Voxpilot VXML server (RFC 4240)
I have been trying to integrate OCSG with voxpilot vxml server.
I used ParlayX 2.1 TPC call service to connect a UA and voxpilot, specifying sip uris as
sip:03211234555@172.18.132.29
sip:dialog@172.18.132.21;voicexml=http://172.18.132.21/test/start.vxml
where
voxpilot = 172.18.132.21
ua = 03211234555
media gateway = 172.18.132.29
The above form of specifying sip uri to call voice xml application is mentioned in rfc 4240. And in conformance to rfc 3261, ocsg should pass on the parameters in sip uri as it is.
But OCSG which acts as B2BUA does not send the additional params in the sip uri i.e. voicexml page to call, while sending SIP INVITE to voxpilot.
