[cisco-voip] CUBE ringback problem

[Brandon Phelps]

Situation: PSTN originator gets no ringback on calls when they are being 
transfered from Unity to ip phone.

Topology:

PSTN---Verizon---(sip)---CUBE---(h323)---CM_6---Unity


I get ringback when I initially call in, just not on transfer. The CUBE 
is doing transcoding from g711 to g729 on box (using the funky telephony 
services config).

I assume it is some interworking thing that someone has already 
experienced. Anybody seen this?

Here is the interworking and transcoding config:
