Resolving Audio IP Address Auto-Detection Problems

If the PC on which Cisco IP Communicator is running uses an unsupported software VPN

client, audio IP address auto-detection will not work. The resulting symptom is one-way

audio.

In this case, you need to complete the following tasks:

?First, run the Cisco IP Communicator Administration Tool and select the option to enable

the HTTP access. Doing this creates a getIP.asp reflector web page. (See the "Running the

Cisco IP Communicator Administration Tool" section on page 2-14 for help.)

?Next, specify the location of the getIP.asp web page in the Cisco CallManager

Administration (Device > Phones > Phone Configuration > Product Specific

Configuration > IP Address Auto-detection URL).

By default, getIP.asp is stored here:

http:///communicatorloads/communicator/getIP.asp

If you want to change the location of the getIP.asp reflector web page, copy the getIP.asp

from the default location, place it in a new location, and enter the new URL in the Cisco

CallManager Administration (see the second bullet above). If you choose to change the

location, be aware that getIP.asp must be placed on a Microsoft IIIS Web server to work

properly for auto-detection purposes.

Tip Audio IP address settings can be viewed and configured from the Cisco IP Communicator

interface by choosing: Right-click > Preferences > Audio > Network... > Audio

IP Address.
