Ankit Mittal updated ASTERISK-20748:
------------------------------------

    Status: Waiting for Feedback  (was: Waiting for Feedback)

@Michael L. Young, Yes I have a setup as you described. This problem is not for a single client but it is for all of the clients who have setup the PBX phones at their ends.

Even DAHDI system was not receive the dtmf digits before, but when I change my dsp setting as previously define, it starts receiving but still it ignore few digits mostly 3.

One more problem occur for all of the PBX client, that tempo of the wav file(which have play at our end) got increased automatically.

> When some one call on our DAHDI(asterisk) system by their landline phone or the mobile phone the call goes perfectly and asterisk accept each of the dtmf digit pressed at other end.
> but when the same call is done by their PBX phone, the system ignore some digits like when we press 100136972 it shows 100192, and if we do it again it shows 1001392.
> I have tried
