[Asterisk-Users] IConnectHere and DTMF

[John Todd]

In short: I know of no way to get DTMF working through a Cisco 
ATA-186 (SIP) and Asterisk to anything other than the X100P port.

What kind of equipment are you using?  I've tried my Cisco ATA-186 
(v2.15) in various settings (in-band, out-of-band, out-of-band-with 
negotiation) and none of them work.  Asterisk can see the DTMF, but 
can't send it. (actually, after the last CVS I did earlier yesterday, 
I no longer even see the "DTMF pending" and "DTMF sent" messages on 
the console, but I hear the static when I hit keys on the ATA-186 
phone.  I now see "Difference is 1928, ms is 40792" type messages 
when I hit DTMF on the ATA)

I've experimented with my own Cisco gateway (12.2(12) on a 3640) and 
have been unable to get DTMF to work, despite various settings on the 
ATA-186 and configuration options (dtmf-relay) on the 3640.

Whenever I send DTMF from PSTN -> 3640 -> * -> ATA, I can see this 
message on the console:

NOTICE[27662]: File rtp.c, Line 300 (ast_rtp_read): Unknown RTP codec 
19 received

I can hear the DTMF, but it doesn't do anything (doesn't work in any 
menus I create.)

Yes, I've followed the instructions on 
http://www.djernes.org/~shawn/ata186.htm  - no luck.  I've even 
followed the instructions on 
http://corp.deltathree.com/productsandservices/devices/ATAConfiguration.doc 
with no success.
