Good point, thanks, But, RFC2833 I've found to be unreliable, broken, patchy, scratchy. I've got it set to RFC2833 now, and it just ain't working. Will get more traces, trial and error until I stumble across a good combo, or bug(s) Thanks again, Mike From: Ognjen Seslija <oseslija@gmail.com> Reply-To: FreeSWITCH Users Help <freeswitch-users@lists.freeswitch.org> Date: Mon, 23 May 2011 20:46:09 +0200 To: FreeSWITCH Users Help <freeswitch-users@lists.freeswitch.org> Subject: Re: [Freeswitch-users] FS - DTMF and Cisco CME/UCE Why use INFO when it's only method I know Cisco won't speak (2833, kpml, sub/notify)?

Hi,
This is driving me nuts. I have a Cisco CME (a few actually) where I cannot get DTMF to work.
Does someone happen to have the magic recipe of SIP/Dialplan profiles and Cisco config to make DTMF <relay> work?
I spent several very very painful days trying to get RFC2833 to work, using FS to try and generate the tones itself. I ended up with all sorts of codec mismatches, delay,distortion and some really mangled DTMF tones
So, now I'm back to;
PSTN----CiscoGW----<external>----FS----<internal>----<CUST PABX>---Phone
Where <CUST PABX> is 3 CMEs that won't talk DTMF 30+ other vendor's gateway's that WILL do DTMF
Context External and internal are both set to dtmf-type info (or dtmf_type info)
DTMF works FROM the Cisco GW towards our network, doesn't
So, does anyone have a magic solution? Because Cisco TAC say they see DTMF being sent (as rtp-nte), when I need INFO or in-band.
Thanks, Mike
