I have noticed a problem with the Cisco 7940/7960 phones where if
you put your voice-mail box on hold using soft keys and come back
you can no longer navigate. I am curious if anyone else can
duplicate this problem. Happens reliably for me with the 7940
phones.
I use rfc2833 for DTMF. I would think it was a Cisco bug, but
for the fact that this did not happen with older version of
Asterisk.
I just tried changing the dtmfmode to rfc2833 for my Cisco 7940G phone
and was able to replicate the problem. I've also found the same
problem with my 7905G phones.
The problem is fixed by changing the dtmfmode to inband on Asterisk.
On the 7940/7960, you might also want to place the following in
SIPDefault.cnf:
dtmf_inband: 0
dtmf_outofband: avt
dtmf_db_level: 3
dtmf_avt_payload: 100 ; Default 100
-- Following is for 7905G phones, but included for reference.
On the 7905G it's slightly more complicated if you're not familiar
with bitmap values. Change bits 4 and 5 in the AudioMode value to 0. I
personally use: AudioMode:0x
You will also need to change dtmfmode to inband on Asterisk was well.
That also fixes the error message about RFC3389 support incomplete.
