CUCM allocates a HW MTP for the H.323 GW since it uses FS for another devices. So far some faxes works and others dont' but what is common to all failed faxes is that the CED tone is being recieved after 20 secs. Here is the isdn debug:
NOTE: I received the H225.0 INCOMING PDU releaseComplete : from CUCM that's why the GW sends the Disconnect. Clearly CUCM doesn't know that this is a fax call. For CUCM is just a call that keeps in the alerting state.
What I haven't figure out if is the CUCM h225 stack process or the SCCP process (for the IOS MTP) that is sends the release, it looks like there is a timer either in H323 or the SCCP or could be both, where the call cannot be too much time in the ALERTING state before it triggers the disconnect.
So any of you guys/girls know what is the timer in H.323/CUCM or in the IOS MTP/Xcode

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
