[Freeswitch-users] double dtmf

Hi,

I too have the same issue.  When calling from  PSTN number,  the freeswitch
says  Incoming call  from "0000000000"  instead of the actual number.
Moreover it detects only few digits (say 2 or 3)  not all the dtmf
numbers.

Please let me know if you have addressed this issue.
