I have an ISR gtwy with a mgcp controlled PRI (from PSTN) and an FSX/DID card communicating H.323 to UCM Business Edition 6.0. The FXS handoff is to a Faxpress server, in UCMBE I have a route pattern pointing to the h.323 gtwy. Faxes hit the Faxpress server but are continuously sent to the default Unaddressed box because the DTMF tones are not being sent. I have tried just about everyhting from going all MGCP back to H.323 and making my adjustments on the dial-peers. Is their any know bugs with UCMBE 6.0?
