I don't think this is a bug. I ran into almost the same thing. Try this.  on CUCM int the sip profile, add the "Send PRACK for all 1xx messages".  you may also need to force early offer on the gateway.

I did a bit of digging, and the remote end played their IVR and expected input after an ISDN PROGRESS, without ISDN CONNECT. From what I read ISDN PROGRESS is only for the other party to play a recording, not receive any audio, so the GW didn't consider the call set up and wouldn't send DTMF.  I got the DTMF working by changing the relay mechanism, but I just tried with Jabber and I experience the same problem as you do.

This is obviously some type of toll-charge avoidance.  I have tried calling from my cellphone and the behavior is the same…phone still displays “calling” even though the AA is connected.
