[asterisk-users] DTMF troubles

[Jason Lixfeld]

I've been using one of the popular asterisk ISO distributions for a  
couple of years and DTMF had always worked.

I recently switched to another asterisk ISO distribution, and outbound  
DTMF is no longer working.

After doing a bit of digging, I noticed that the new distribution  
wasn't setting any sort of dtmfmode at all, anywhere.  The old  
distribution had rfc2833 set in sip.conf for the phone extensions, so  
I thought I'd set the dtmfmode and see if that helped.  Unfortunately,  
it did not.

I then went ahead and set dtmfmode=inband in sip.conf and iax.conf for  
the phones and trunk to provider, respectively.  At that point, I was  
finally able to hear DTMF tones when I called out to my cell from my  
7960 but they still weren't enough to trigger the menu of an IVR  
outside of the * system.  Jitterbuffer is disabled on the IAX trunk to  
the provider.

DTMF seems to work fine from the phone to *, because I can trigger  
menus on my own IVR without a problem.

I don't specifically recall the minor, but I know the old asterisk  
distribution major was 1.2.  Maybe the minor was high 20s, 30s.  Who  
knows.  The new distribution is 1.4.23.1.

I upgraded my 7960 from 8.6.0 to 8.11.0 with the transition to the new  
distro, so perhaps that's an issue.

(FTR, my call path is: SIP from the phone (7960) to *, IAX from * to  
the provider.)

Any ideas?
