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.

Subject: [Asterisk-Users] problems with DTMF
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
