------------------------------------

Ankit, can you try DAHDI 2.4.0 ?
I have problems with DTMF and DAHDI 2.5 - 2.6 in a busy machine.

> 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 
> 1. relaxdtmf = yes /no
> 2. toneduration = 300
> but nothing help me.
