No digits are passed from cellphone or your home phone but when you press any key from your registered IP phone on local lan, digits are passed very well,
what is the problem? This problem is new and beforehand i had no problem with dtmf from cellphone!
Every thing is good, all logs are good, my IVR that gets digits and transfer calls are good and no problem exists in these aspects.
May my trunk filter, kill, resolve or delete all DTMF or kpml signals on sofia sip?!

Is problem from some configuration in sofia?! any idea?
my provider(trunk and ...) uses cisco IPPBX and i use FS certainly.
