I had a similar issue with the Ciscos. I just a warning. Its fixed on master. See http://jira.freeswitch.org/browse/FS-4923 On Apr 22, 2013, at 1:10 PM, Sean Devoy wrote:
HI, I submitted a jira because people get yelled at for not sending a jira on ERRORs.
However, I really think this might be a Cisco SPA504G setup issue.
I get “[Err] switch_rtp.c:389 Failed DTMF payload check” when I dial OUT and hit an IVR where I have to enter DTMF numbers. My latest was entering CC number, the response I got was “You entered 4”, the first of 16 digits I typed!
Cisco has some parameters for DTMF and my are set thusly: DTMF Playback Level: 0 DTMF Playback Length: .1 and Inband DTMF Boost: 6dB.
Could those values be incorrect or hindering the process?
Thanks, Sean
