If you experience one way audio while you make calls through Cisco IP Communicator, you need to check the connectivity between the IP Communicator and the gateway. If you cannot ping the gateway from the system on which IP communicator is installed, it can be due to some configuration issue, for example, Routing, Access-list and so forth, or due to some firewall configuration. If there is a firewall between IP Communicator and the gateway, make sure that the ports are opened in the firewall. Install and Configure IP Communicator with CallManager:
I have the same issue, but in my case, when I use IP Communicator, then I get no issue over VPN, but when I dial outside from my personal communicator over vpn then I get one way voice, the remote party can hear me, but I can't hear them properly! I am using ASA 5520 and cisco VPN client software!
It seems to me that this could be the issue with SIP protocol over VPN, cos personal communicator uses SIP and presence server, and IP communicator uses SCCP, but still I am looking where the issue is!
