oInbound Call Answer: This field sets the destination to terminate all incoming calls from the trunks listed. The call can be terminated into the
direct extensions, hunting/ring groups or the conference bridges (pending).
oSession Keep Alive: This field allow users to enable or disable the usage of the
session timer. This is enabled by default to: Automatic/Session Timer. The session timer enables SIP sessions to be periodically “refreshed” via a SIP request. When enabled, before the session interval expires, the GXE502X will send a SIP re- INVITE message to the SIP server. If there is no reply to this message the session will be terminated. This will avoid stalled sessions occupying the channel/bandwidth.
oSession Expiration: The Session Expiration is the timer (in seconds) at which the session is considered timed out if no successful session refresh transaction occurs beforehand. The default value is 180 seconds. Incorrect configurations could cause
calls to be dropped Or suspended.

4. Conference Bridge
The GXE502X supports 2 (GXE5024) or 4 (GXE5028) password protected conference bridges that allow up to 12 (GXE5024) or 20 (GXE5028) simultaneous participants from PSTN trunks, SIP trunks or Internal Extensions.
The Conference Bridge/Room numbers are configured automatically by GXE502X during the Express Setup process. At the factory default settings the conference bridges do not have password protection. Users can change the extension numbers of the bridges and set a password to by selecting the Conference Bridge menu.
•Renaming the conference bridge extension numbers and passwords:
To rename an extension number on a conference bridge, enter the extension number (please make sure the number is not currently in use by a local extension) into the Extension field of a conference room. If you want to require users to enter a password before they can enter the room, input a numeric password in the Password field. When done, click the Submit button to save the changes. The changes will be written into the Flash memory and will take effect the next time the GXE502X is rebooted.
