[asterisk-users] No DTMF on Sip Trunk?

[Noah Miller]

Hi All -

For the first time, I'm setting up SIP trunking between two asterisk
boxes.  The calls themselves work fine, but I'm not able to get DTMF
working.  I've tried using inband, rfc2833 and auto, and none of them
work.  Maybe I'm missing something obvious?  Here's my config:

Asterisk1 (1.2.18):
sip.conf
[129trunk551]
type=friend
secret=********
username=129trunk551
host=xxx.xxx.xxx.xxx
context=phones
dtmfmode=auto
qualify=1000
disallow=all
allow=ulaw
insecure=very


Asterisk2 (ABE revC):
sip.conf
[129trunk551]
type=friend
secret=*******
username=129trunk551
host=yyy.yyy.yyy.yyy
context=default
dtmfmode=auto
qualify=1000
disallow=all
allow=ulaw
insecure=very


Thanks,
Noah
