Testing was done with SJphone for Mac, dtmfmode rfc2833 pt 101. Hopefully this debug log can help: http://pastebin.freeswitch.org/9374 If I need to add, change, whatever, let me know. Thanks for the help. -benj Brian West wrote:
What device are you using? RTP traces, debug logs something to see what might be taking place.?!?!

Hi all,
We're running into a problem with rfc2833. Here's the situation:
A registered SIP endpoint sends DTMF as rfc2833 to our FreeSWITCH. The FS console shows it receives the digits once. We send the call to a tier-1 carrier The digits are played read back, but often the first several digits are repeated, i.e., 'Sorry, 1, 1, 2, 2, 3, 4 is not a valid password' when the user entered '1234.'
When I was testing this recently, the call was sent to a Cisco gateway, which the documentation* states has problems with rfc2833, just like Sonus gateways, although that should be fixed past revision 10744.
When using inband, everything works great. We are using start_dtmf_generate in the outbound dialplan. DTMF to tier-1 providers is inband. My initial thought was that the tier-1 was receiving rfc2833 and inband, but it's not consistent.
I'm sure more information will be requested of me to help troubleshoot, so please let me know. Any advice would be very much appreciated.
