[asterisk-users] DTMF Corruption Problem

Asterisk People,

I'm currently using Asterisk and with a SIP voip provider and I'm
having problems where DTMF input in my IVR app is getting corrupted
intermittently.

For example, if someone enters 1025, it may come though correctly as
1025, or it may come trough as 10025, or 100255.  DTMF digits will
just double up.

This doesn't happen all the time.  Asterisk will just pick times to
not be very friendly with DTMF, and other times it will just work
flawlessly.

I'm using RFC2833 on:

Linux hostname 2.6.9-42.0.2.ELsmp #1 SMP Wed Aug 23 00:17:26 CDT 2006
i686 i686 i386 GNU/Linux

with Asterisk 1.2.13.

Also, I am not using a zaptel timer.  Could this possibly be causing
problems with DTMF??

Thanks!
