[asterisk-users] Re: DTMF Corruption Problem

[Justin Tunney]

UPDATE:

I've installed ztdummy and have chan_zap.so loaded in to the system so
Asterisk can use psuedo zap channels or whatever it does for timing.
I also specified relaxdtmf=yes in sip.conf.

DTMF is still completely awful.  Digits are still getting doubled up
and my IVR is still nearly impossible to use.

I'd like to note that I'm using Bandwidth.Com (A Level3 reseller) for
SIP VoIP service.  I did not experience this problem before with my
old VoIP provider Gafachi.

Does anyone have some tips on trying to debug this further?  Are there
any commands I can put in to tethereal that will give me debug
information on RFC2833 in the RTP stream?

Thanks,

Justin Tunney
