[Freeswitch-users] DTMF recognition flaky

Hi Jay,


Have to say my DTMF works flawlessly on thousands of calls.  (SVN trunk
from a couple of days ago.  We handle around 100,000 calls/day via FS)


That said, I've found it depends on your SIP trunk provider.    That
doesn't mean to say there isn't a problem; it's just that I haven't come
across it.  


Know it's not helpful, but there you go.

I'm running 1.0.4pre3.  Haven't gotten a chance to upgrade to pre7 yet.


2833 is the default right?  I haven't changed anything.  I'm using
voicepulse for my SIP trunks.  Is there an option I can add to that
definition to force RFC2833?

Well it depends.. first off are you doing inband dtmf or RFC2833?
Secondly what SVN rev are you running?

Using the default installation, I've noticed that when I (or someone  
else) calls in on my SIP trunk and keys in an extension, not all of  
the numbers are recognized unless they hold the key down for at least  
1/2 second to a second.

Is there a way to improve DTMF recognition so people can just type in  
stuff without having to hold the keys down?
