7936 phone - no audio

[jrchgtrrz]

Has anyone run across this? We have 3 7936 phones in conference rooms. When we place calls on any of these sets, the connection is made and the remote party can hear us, but not vice-versa. We cannot hear the remote party through the 7936. The phones were reset and the problem went away. Any ideas? I'm running CCME 3.2.1 on a 2811 router.

Configure 'voice rtp send-recv'

Because voice path is established in the backward direction as soon as the RTP stream is started. The forward audio path will not be cut-through until the Cisco IOS gateway receives a Connect message from the remote end. In some cases it is necessary to establish a two-way audio path as soon as the RTP channel is opened.
