[Asterisk-Users] TDMoE and Badness in Kernel

[Ed Pringle]

Hi,

I am having the same problem on 2 machines running suse 9.3 kernel 2.6.11.4-20a
I was hoping that TDMoE would solve some problem that I am having using IAX2.
As IAX2 takes the DTMF outof band the timing of the signal is not quite the same
as the original and creates problems for other equipment.
