We are facing a one way audio problem using Cisco 6961 over a VPN tunnel.
Not NAT is used. The ipphones on the remote site can't hear the users from the HQ where the CUCM is deployed.
The stange thing is is working fine when we use IP Communicator softphone instead of the hard ip phones.
Both (CIPC and 6961) are in the same subnet .
Any idea is welcome.
Thank you in advance
