Administrator’s Guide for the V500 System
Configuring Call Preferences
Call preferences help you manage the network bandwidth used for calls. For example, you can specify the default and optional call settings for outgoing calls, and limit the call speeds for incoming calls.
If you have just set up your network, use the screens described in this section to specify your call settings. If your network has been set up for some time, but you notice that your call quality is not optimal, you may want to change some of these call preference settings to increase the quality of your calls.
To configure your call preferences:
1.Go to System > Admin Settings > Network > Call Preference.
2.Configure these settings:
Setting | Description |

Enable H.329 | Check this to specify |
| collaboration. |
