[Asterisk-Users] problems with DTMF

[Bjorn Asmul]

Hi Will,
 
You should use the standard rfc2833 as suggested.
Also be aware that using "ulaw" will always switch to "inband" DTMF
mode, but the phone and Asterisk should automagically detect this.
 
Btw: Cellphones and DTMF just doesn't work well together.
If the cellphone is in a poor reception area, it might not send DTMF
tones correctly.

Hi,

I'm struggling a bit with DTMF.  It seems to work fine on my internal
network, but when I call outside lines with telephone trees, some
systems understand the DTMF and some ignore it.  Anyone have tips on
solving this?  Thanks in advance. 

My local phone is a Grandstream GXP-200

And my provider is BroadVoice
