[asterisk-users] no dtmf pcom 650 only outbound calls

[Dovid B]

Your problem is 1.2.X. It has a poor DTMF. I  broke my head for a few weeks 
on the same issue. (My issue was Polycom + Asterisk 1.2.X + provider X. The 
interesting thing is that the Polycom + asterisk worked fine. The issue I 
had was just when I was calling out through a specific provider.) Any other 
phone worked. The following patch worked for me: 
http://www.h6315.com/dtmf.patch

I would like to add that for some reason the patch did not work on all 
systems that I tried to apply it to. (I am not  a coder so I was not able to 
trouble shoot the reason further.)
