On the Call Options page, you can enable call features, such as Auto Answer and requesting a password for incoming calls. You can also select the protocol to use during calls, configure DNS lookup and other network settings. To achieve the best video and presentation quality, you can select the appropriate mode for primary and secondary video streams.
Procedure
On the Settings menu, go to Call > Call Options.
On the Call Options page, to enable the Auto Answer feature for incoming calls, select the Auto Answer check box.
If you disable Auto Answer, you receive a dialog box for each incoming call to the codec, requesting you to accept the call. With Auto Answer enabled, all incoming calls are automatically answered, and you do not need to accept them.
To set up a password for incoming calls, select the Refuse The Incoming-call Automatically When The Password Does Not Match check box.
You can define the password for incoming calls for security purposes. To call the codec, the user must dial <codec IP address>##**<password>. The codec blocks the incoming calls with non-matching or missing passwords.
If you enabled the password for incoming calls, in the Incoming-call Password field, type the password.
You can type a maximum of 32 alphanumeric characters.
To use the secondary video stream when there is an active presentation from another codec or video endpoint during a conference, select the Grab Presentation check box.
When Grab Presentation is not enabled, the secondary video stream must be idle before the codec can take control.
This feature applies to H.323-based conferences. When using the SIP protocol, the codec can take control of the secondary video stream at any time.
To manage remote cameras during a call, select the Enable Farcamera Control check box.
To translate readable domain names to IP addresses and port numbers through DNS SRV records, select the Enable Lookup From DNS SRV Record check box.

For the Default Call Rate setting, select the default call bandwidth in kilobits per second.
For the Maximum Transmission Bandwidth setting, select the maximum bandwidth for transmitting data during calls.
For the Maximum Receiving Bandwidth setting, select the maximum bandwidth for receiving data during calls.
For the Presentation Bandwidth Percentage setting, select the bandwidth percentage that the codec takes from the main video stream bandwidth and uses for presentations.
For the Primary Video Mode setting, select one of the following options:
Clear: To prioritize image resolution for the primary video.
Smooth: To prioritize frame rate for the primary video.
Very Smooth (only for Avaya Room System C190): To achieve the highest possible frame rate at up to 60fps for the primary video.
For the Secondary Video Mode setting, select one of the following options:
Clear: To prioritize image resolution for the secondary video.
Smooth: To prioritize frame rate for the secondary video.
Very Smooth (only for Avaya Room System C190): To achieve the highest possible frame rate at up to 60fps for the secondary video.
PPT: To prioritize presentation quality for the secondary video.
For the Media Waiting Time setting, select the waiting time in seconds to establish a media session between the endpoints.
For the I Frame Requests Filter Time setting, select the filter time in seconds for intra-frame (I-frame) requests.
For the Interval Time of IDR Frame setting, select the time interval between two I-frames.
