[Freeswitch-users] DTMF in IVR menu

[JP]

I still am facing this problem, but wanted to provide more data in case
somebody has a solution already...

1. The call path is from PSTN --> Asterisk --> FreeSWITCH.
2. play-and-get-digits works fine for multiple dtmf. But for one single
dtmf I see delay in recognizing the dtmf on the FS side.
3. All traffic is RFC2833, no inband.
4. I tried setting "rtp_manual_rtp_bugs=ignore_dtmf_duration", but that did
not help.
5. I see at least one other user had the same problem on the thread (
http://lists.freeswitch.org/pipermail/freeswitch-users/2012-August/086720.html),
but I don't see a final solution if there was any.
6. I looked at a tcpdump from both the Asterisk and the FS boxes, but
nothing obvious jumped at me.

Any help is greatly appreciated.

Thanks,
JP
