No voice on IP phone

Posted by Jim Hagan on April 28, 2009, 10:33 am

We are trying to connect an NEC Dterm IP phone (itr-16d-2) through a Netopia 3347 router into our NEAX 2000 switch. The phone rings but there is no voice. We have configured the Netopia as a full bridge and have confirmed with the ISP that they are not blocking voice ports. I can see the IP assigned to the phone through a ping command and a tracert command. Has anyone else encountered this problem?
