Description:Here's link to problem description:

DTMF for SIP calls works fine for various IVR scripts I've written using Waitexten application. I have ethereal traces from telco showing we receive RFC 2833 correctly. SIP callers to VoicemailMain or Meetme consistently have DTMF failures. Asterisk console shows less than 50% correct digit recognition, but not complete failure. When I put in username 12345, password 12345, the log shows username 2 password 5.

Same calls in via TDM trunks work correctly. Could this be issue with reliance on TDM drivers in zaptel for Meetme and VoicemailMain? I'm not a developer.

I'm using:
Asterisk (it was still a problem in Asterisk
Zaptel (it was still a problem in older versions too)

hardware is TDM04B from wildcountry, don't remember revision (but it was latest one as of June 2006)

I will experiment with using these apps on a box with ztdummy instead of wctdm and report back the results.

1.2 branch has known DTMF issues which were addressed in 1.4, which is in beta-stage right now... Could you please test 1.4-beta2 to see if you still have issues there?

skeagy, were you able to test the 1.4 branch ? Thanks

I've downloaded 1.4beta3 tarball, going to apply in the next day or so on a test machine and can then report back findings within a week.
