Hello,

I am having some problems getting DTMF to work properly for different systems. I have a Grandstream HandyTone 286 ATA. It supports three modes of DTMF:

1- in-audio
2- via RTP (RFC 2833)
3- via SIP INFO

The default is in-audio and it seems to work most of the time. I use G.711 so audio should be OK.

When I call a service via SIP the DTMF are not recognized. For instance sip:7125807050@67.55.158.226 (www.seipmeeting.com).

If I change my settings in my ATA to "via SIP INFO". DTMF works fine calling a sip service. However, my Voxalot Voice Mail breaks, by not accepting my pin.

I also tried with both options selected in the ATA ("in-audio" and "SIP INFO") but Voxalot Voice Mail does not recognize the tones.

I thank you in advance.
