[Freeswitch-users] FS vs provider's Sonus DTMF (double digit) problem

[Dmitry Saratsky]

Hi All,

I'm suffering from dtmf "double digit" problem for incoming calls that
destined to IVR on my FS.
I tryed to identify and workaround the provlem with no success...
I have already tryed to change dtmf-mode, use sonus-fixup etc with no
luck...
I have: FreeSWITCH Version 1.0.head (git-1086cba 2011-05-23 22-51-43 -0500)
I would like to ask you some questions and I'm attaching some relevant
output (see below)

1. According to output (see below), is it right to say, that my provider
sends me DTMF events both in "DTMF INFO" and "RTP DTMF - rfc2833" way?
2. If so, may be this is the reason for "double digit" I suffer?
3. If so, can I filter incoming "DTMF INFO" events in FS?
4. If so, do FS have some workaround for this?

Thanks,
Dmitry.
