DESCRIPTION

Session Timer

Select this to activate the WiMAX Device’s SIP Session Timer. SIP Session Timer

Enable

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.

 

 

Refresh Method

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.
