AA and Mobile line Problem

[m_ibrahim]

i have a CME 4.0 on 2821 and IOS 12.4(11)XJ4 with 8 FXO interfaces ,6 of them are conncted with PSTN analog lines and 2 with GSM Mobile line ( using Prema Cell) .

i configured IVR (AA) on the CME ,the 8 line are under the AA.

the Problem is, when i dial from my mobile to the GSM mobile line ,i hear the ivr message but i can not interact with AA menu ( i does not response to my DTMF signals),

this problem does not exist on the PSTN Line it work good with the aa .

Thanks

Can you try "dtmf-relay rtp-nte digit-drop".Digit-drop will drop in-band DTMF and pass it out of band.
