Ports Used by Cisco IP Communicator

IP Communicator is the same as normal IP phone, so it uses these ports:

  • TFTP (UDP 69)—In order to obtain phone configuration and software

  • SCCP (TCP 2000)—For skinny (SCCP) signaling

  • HTTP (TCP 80)—In order to access IP Phone services

  • RTP (UDP 16384-32768)—For audio


One-Way Audio Problems

One-way audio problems are reported while calls are made through the Cisco IP communicator.

If you experience occasional one-way audio, try to hold and resume the call while the symptom occurs. This can resolve the problem.

Solution 1

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.

Note: If you are have a one way audio issue with a Cisco IP Communicator 2.1(2), upgrade to version 2.1(3). Refer to Release Notes for Cisco IP Communicator 2.1 for more information.

Solution 2

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:

  1. The Cisco IP Communicator party has muted the recording device.

  2. The Cisco IP Communicator party has plugged the headset and speaker plugs into the wrong ports on the PC.

  3. The Cisco IP Communicator party is running another application that uses the microphone, such as a sound recorder or another software-based phone.

  4. 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:

  1. The Cisco IP Communicator user relies on an unsupported VPN. You must set up a web reflector page or manually specify the IP address in the Network Audio Settings window in order to resolve this issue. Right-click and choose Audio tab > Network button.

  2. The Cisco IP Communicator user relies on an unsupported VPN, and Cisco IP Communicator is integrated with a Linux-based Cisco Unified Communications Manager (Release 5.x and later). Run the Cisco IP Communicator Administration Tool on a Windows serverin order to resolve the audio IP address auto-detection problem.

  3. If Cisco IP Communicator is behind a firewall, use the appropriate port range and make sure that the firewall is configured to pass TFTP and RTP traffic.

IP Communicator Users are Unable to View Corporate Directory

IP Communicator users are unable to view corporate directory while connected remotely to the Cisco CallManager.

Complete these steps in order to resolve this issue:

  2. Download the latest version of IP Communicator from this location of IPC .

  3. Choose Service > Service Parameters. Choose the Cisco CallManager server and choose Service > Cisco TFTP. Click Advanced and set false to these parameters and update it.

    • Enable Caching of Constant and Bin Files at Startup*

    • Enable Caching of Configuration Files*


    Note: For Cisco CallManager 5.x/6.x, choose Service Parameters from the System menu in order to change these parameters.

  4. Disable if any windows internal firewall exists. If multiple interfaces are used, disable all other interfaces except the interface which is associated with the IP communicator.

  5. Restart the Cisco TFTP service and verify that corporate directory appears in the IP Communicator.

Registration Rejected Error DBConfig on Cisco CallManager 5.x

You get the Registration Rejected Error DBConfig error message when IPC connects to Cisco CallManager 5.x.

When you try to register an IP communicator to a Cisco CallManager, ensure the Device Name parameter of the Device menu value has the word SEP followed by the MAC address of the PC in which the IP communicator is running.

Complete these steps in order to resolve this error:

Choose Phone from the Device menu and then choose Add New and IP Communicator from the Phone Type drop down list. Next, enter SEP<MAC address> in the Device Name field and Save it.
