We have some custom H.323 endpoints that we are using with Cisco IP Telephony (CCM+gateways) and in the case of a call redirection we would like to show the original called number as well as the calling and called number.
We know that Cisco sends the OCN data in the H.225 SETUP message as nonStandardData, but we don't know how to decode that information.
In H.323 V4 that information is sent as standard data, but we need to know the "nonstandard" method because we are using a h323 v2 stack.
Re: Original Called Number in H.225 nonStandardData
The H.323 Version 2 gateway propagates the entire RDN or OCN IE from an incoming PRI message into the H.225 SETUP message. The IE is encapsulated in the nonStandardData field within the user-to-user information element (UUIE) of the H.225 SETUP message. The nonStandardData field contain the encapsulated RDN or OCN IE and a tunneled QSIG message, or it contained only the OCN or RDN. Cisco and other third-party H.323 endpoints can access the redirected information by decoding the nonStandardData field. In accordance with the H.225 specification, the nonStandardData is ignored by third-party endpoints and caused no interoperability problems.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
