With both external and remote, i mean that the ivr doesn't belong to my company, but sits out on the PSTN. i have already unchecked the "Wait for Far End H.245 Terminal Capability Set" box. the topology is as follows:
Cisco IP Phone==>CUCM6==>h323 Gateway (3640)==>PSTN (through E1 PRI)
i think that the problem lies between the CallManager and the gateway, because debug h245 asn1 doesn't show dtmf being received by the gateway.
problem is fixed, and to tell you the truth, the solution is pretty embarrassing. i have two voice gateways at this particular site, one for routing pstn calls, and one for routing cellphone calls. one of the junior guys had added a more specific route pattern to the cellphone partition, which forwarded all the pstn numbers for the external ivr's to the cellphone gateway, which isn't set up for dtmf relay. once i had corrected the route patterns, everything started working normally.
anyways, thanks for your interest, i really appreciate it!!

the softkeys. You enable or disable them via TCL. Here is the long
