[Asterisk-Users] Cisco 7940 no audio

[Craig Waddington]

I will try disallow=all, thanks, Nat is off. Sip.conf below.

If I call from my mobile to the isdn number, the Cisco phone rings, I pick up, they can hear me, I can not hear them, if I transfer it to the Sipura I get AUDIO!! .... 

It is also happening over IAX with the Cisco phones.

I followed a lot of the examples on loligo.com, which were a great help, but this is so hard to troubleshoot as I cannot see any errors in debug, asterisk thinks a good call is in progress.

Anything internal is perfect. The CAPI works fine. Its just the audio from the other end.

Every now and then I can hear a quick bit of sound. One in 20 calls may work.

[general]
port=5060			; Port to bind to
bindaddr=0.0.0.0		; Address to bind to
allow=ulaw
allow=alaw
tos=lowdelay


[20]
type=friend
username=20
secret=20
canreinvite=no
host=dynamic
mailbox=20
callerid="Cisco Phone" <20>
accountcode=20
qualify=yes
context=sip

Thanks.

Make sure you don't have the Cisco phone set to do NAT.
