I'd like exchange faxes between 3rd party H.323 gateway which requires to use T.38 fax relay and ATA which doesn't support T.38. ATA is controlled with SCCP by CUCM 6.0 and there is H.323 trunk between CUCM and 3rd patry GW.
My idea is to use CUBE (IP-IP GW) but it looks like it doesn't support fax protocol transcoding.
Can anyone confirm if this feature is supported on Cisco UBE?
Your suspicion is correct, Petr. CUBE does not support T.38 fax to fax passthrough transcoding.
The type of transcoding that CUBE will do is for example one leg of the call uses G.711 and the other leg using G.729, and then overlaying a T.38 or fax passthough fax on top of that session. Both call legs on the CUBE, however, would need to use the same fax protocol.
I have triedto setup a solutionthatforcedthedial-peerto the OXE side inT38and theOperatorinG711abut does not work,and I see in thetracesthatcan notforce theprotocol(the callcomes fromOXEinT38and goes to theoperator in T38and the other way the call came from the operator in G711Aand goes toOXEinG711A).Therouteris not doingnothing, does not interworking.
