SIP Session Timer is a function used by both of the communication peers to determine if the call session is still active (alive) or not. It uses the method specified in the following Refresh Method field to periodically refresh the SIP sessions. Select the method to be used for periodically refreshing SIP sessions, to determine if the session is still active. Select UPDATE to use Update requests to refresh the session and select INVITE to use Re-Invite requests. You should use the same method as the peer device. The Update method uses less overhead than Re-Invite, but is not as widely supported as Re-Invite. By default the WiMAX Device is set to use the UPDATE method. When set to UPDATE, the WiMAX Device can also revert to using the INVITE method for SIP session refresh, depending on the method supported and allowed by the peer device. 9.5 Speed Dial Speed dial allows you to use a shorter number for dialing frequently used phone numbers.
