[Freeswitch-users] FS - DTMF and Cisco CME/UCE

[Mike Taylor]

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 tonesŠ

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 DTMFŠ

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
