After first launch, no extension number appears and the status line area shows "Registering"
Make sure that you chose a TFTP server, if necessary. Your system administrator should provide you with the TFTP address if one is needed.
If you are a remote user, make sure to establish network connectivity before you launch Cisco IP Communicator.
After launching, Cisco IP Communicator cannot locate your network adapter and asks you to reinsert it
Replace the missing network interface device, if possible. (For example, replace a wireless card or a USB Ethernet adapter.)
If you first launched Cisco IP Communicator on laptop that was connected to a docking station, try docking to see if this fixes the problem. If so, ask your system administrator to help you configure your device name so that Cisco IP Communicator will work without the docking station attached.
If you have permanently removed or disabled your selected network adapter, coordinate with your system administrator before selecting a new adapter.
Your audio device does not show up in an audio mode drop-down menu
If the device is a USB handset, USB headset, or sound card, make sure that the device is properly installed and re-launch Cisco IP Communicator. (Devices installed after launching are not recognized until the next launch.)
If the device is an analog device, it will not appear in the audio mode list because analog devices are extensions of your sound card. Choose your sound card instead.
After launching, Cisco IP Communicator shows no extension number or the wrong extension number
Contact you system administrator for assistance.
You might have selected the wrong network adapter. If you have multiple adapters and are prompted to choose one immediately after installing Cisco IP Communicator, choose the adapter that is most likely to provide permanent connectivity or is always enabled--even if it is not plugged in. Your system administrator can tell you which adapter to choose.
Note that the network adapter setting allows Cisco IP Communicator to identify itself to the network; it is not used for audio transmission. For this reason, do not change this setting once it is established unless you are permanently removing or disabling the selected network adapter. In this case, coordinate with your system administrator before selecting a new adapter.
Choose right-click > Preferences > Directories and enter a username and password (Your system administrator can tell you what user name and password to use.)
If you want to search your Personal Address Book using Quick Search, you must also choose right-click > Preferences > User and enter your user name.
Adjust your ringer volume by clicking
on the Cisco IP Communicator
interface when no calls are active.
If you use a USB handset, do not select it to serve as your ringer. In general, you should choose your sound card for the ringer.
If your sound card is selected for ringer mode, and a headset is plugged in to the audio jacks on your computer, then you must be wearing your analog headset in order to hear the ringer.
