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 mentioned in the previous section are opened in the firewall. Refer to ASA 7.x/PIX 6.x and Above: Open/Block the Ports Configuration Example for more information on the PIX firewall configuration in order to open the ports.
If the remote party cannot hear the person who placed the call on a Cisco IP Communicator, it can be for one of these reasons:
The Cisco IP Communicator party has muted the recording device.
The Cisco IP Communicator party has plugged the headset and speaker plugs into the wrong ports on the PC.
The Cisco IP Communicator party is running another application that uses the microphone, such as a sound recorder or another software-based phone.
The Cisco IP Communicator audio settings are incorrect. See the User Guide for Cisco IP Communicator for more information.
If the Cisco IP Communicator party cannot hear the remote party, it can be for these reasons:
