Re: Interoperability Issues

That's not related to the terminalCapability set. You need
to set Facility body to empty for V1,2,3 endpoints (some work
without this, some does not) when sending H.245 tunneled
messages. The V4 recommendation requires the body 
to carry Facility_UUIE with reason code set to transportedInformation.
The problem is that some older endpoints receiving Facility
with non-empty body think it is a call redirection.
