This bit me too. Had to turn nat off on the 7960Gs

Guys......

I have Asterisk CVS-NHEAD-03/19/05-21:56:28 running on a box here and have a couple of Cisco 7960s and a Grandstream phone.

I can make calls from the 7960. When I get a call placed to the 7960 the call is setup but there is no audio in either direction. This is for a call placed on the local subnet between extensions so I doubt that it is a NAT issue though I have tried a number of combinations of this to no avail.

I have tried firmware versions 6 & 7 on the Cisco phones, same result. I have tried the phones on two other Asterisk installs and they work fine. I have compared sip.conf with these and can see no differences.

If I configure the grandstream up to replace the 7960 it works fine.

I have noticed that the src port (TCP port on the phone) increments during the session which seems to be the issue.

Anyone seen this before? Any assistance would be appreciated.

Regards
Peter


Peter,

This one bit several of us. Upgrade to CVS-Head as of 3/22/2005 or later.
