[cisco-voip] Cisco IP Communicator Issue

[Cristobal Priego]

most of the times one way audio issues are related to routing problems than
an issue with the CME, CCM or the phone.
and its more common to have a one way audio issue when a vpn tunnel is
involved. could you please check your routing table.
what i'd check is the routing table or whatever you have on the vpn. it
looks like the traffic coming from your office to your ipc is getting lost
somewhere that's why they can hear you but you can't hear them
