[Freeswitch-users] DTMF not passed through to client

[Johannes Jakob]

Hi,

Just to give feedback:

problem solved by updating to last git head, although I didn't find a significant change in the revision history about dtmf stuff except this one:
http://fisheye.freeswitch.org/changelog/freeswitch.git/?cs=b53a68484361c9581a26f6b090a58b0803bd412d

FreeSWITCH Version 1.0.head (git-7847289 2011-02-19 23-38-04 +0100)
=>
FreeSWITCH Version 1.0.head (git-8fe24a2 2011-03-04 12-28-41 -0600)


Thanks anyways for your thoughts!

Greets,
  Johannes
