Hi,
We have some queries related to Fax support at Gateway using H.323 Annex-D and T.38.
- How the originating gateway (after detecting CNG) tells/informs the destination Gateway, that the call is a fax call [assuming two gateways are communicating using H.323]
- How do we open logical channels for fax communication (T.38) - Annex-D tells that openLogicalChannel can specify TCP/UDP option in the OLC structure - which parameter tells TCP/UDP option in OLC? is it the media transport type in transport capability ? - what kind of capability is specified for fax - is it voice/data ? or a separate capability structure?
Any kind of information, help or pointer would be highly appreciated....
