IP Communicator 2.0(2) with CCM 4.1(3)sr2 over VPN connection.
If both sides over VPN connection are IP Communicators, then we experienced one-way audio on the internal side(where CCM located); if internal side is a fixed IP Phone, there is no one-way audio issue.
I know this is a common problem, most likely it related to routing/traffic block issue. But in my case, when internal side, it is a fixed IP Phone, it can work fine.
When I disabled the CUVA on the both LAN and VPN ends of IPC, then the IPC on the CCM(LAN) side can not hear any audio from the IPC on the VPN Client, but on VPN side, I can hear the audio from the LAN side IPC; If I enabled the CUVA on both sides, then both ends IPCs, sometimes, we can hear each other with Video, and sometime, the LAN side can not hear VPN side with or without video.
