| Auto Answer | If disabled, you must manually answer or ignore incoming calls. | Disabled |
| Auto Answer Mute | If enabled and Auto Answer is enabled, the system is muted when a call connects. | Enabled |
| Auto Bandwidth | Addresses how the system responds to packet loss during a call. When enabled, the default, the system attempts to use the best available bandwidth after the call connects. | Enabled |
| Maximum Call Bandwidth | Sets the maximum amount of network bandwidth to use for each incoming and outgoing video call. This value becomes the maximum value that users can choose from the Dialer when they place a call manually. This value also sets the maximum receive bandwidth for any video call independent of the value of Maximum Call Transmit Bandwidth. | 6000 kb/s |
| Maximum Call Transmit Bandwidth | Sets the maximum amount of network transmit bandwidth to use for each outgoing video call. This value cannot be greater than Maximum Call Bandwidth. | 6000 kb/s |
| Default Call Bandwidth | Sets the amount of network bandwidth to use for each outgoing video call when the user specifies Auto for bandwidth when placing the call. | 1328 kb/s |
| Secondary Stream | Enables H.239 capability, allowing you to send and receive presentations on a second stream. By default, a secondary stream is enabled. Consider disabling the secondary stream if your system experiences issues with third party systems that do not support a secondary stream. If the video call does not support secondary streams (because the secondary stream function is disabled on the near end or the far end does not support secondary streams), the primary and presentation input are automatically swapped so that the presentation appears to all callers. | Enabled |
