You should consider Patton SN4961.I am no shareholder of Patton, but those boxes work so great and are quite cheaper than the competition, that it is hard to imagine why anyone would buy something else...

_______________________________________________Hello,I had for a long time a Cisco SIP-E1(with Q.sig) gateway which caused me much grief with DTMF; it works partially OK with INFO but not with RFC-2833. I filed a support call with Cisco, as its debug shows that it receives and detects the RFC2833 but nothing is sent to the E1 side.The last conslusion of Cisco's support is that I have to enable transcoding but they coouldn't find how to enable it in my configuration. I now have an Audioodes Mediant-1000 on loan which does RFC-2833 without any problems...The only problem I've found so far with the AudioCodes is name passing via E1/Q.sig at the ringing phase (we use it to connect our Freeswitch to our Nortel PbX).Regards, __Yehavi:
2011/5/24 Mike Taylor <mtaylor@employees.org>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

Here's the CME snippet for FS trunk I have. FS sends 2833 tones to CME btw.
dial-peer voice 100 voip
description ** TO FS **
destination-pattern .T
b2bua
session protocol sipv2
session target sip-server
session transport udp
dtmf-relay rtp-nte
codec g711alaw
no vad

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 DTMF30+ 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
