Unregister and delete the selected extension from the AP20.
Enable the registration mode in the AP20 for the selected handsets. The
registration mode stays active for about 4 minutes so you have time to start the
registration process in the ML440 handset. See Step 6. Register the ML440
handsets with the AP20 and the DSX . on page 8 in the Installation Checklist
for more.
Deregister the selected handsets. This does not delete the extensions from the
AP20 - it only deregisters (disables) them.
Enter the LAN IP address of the DSX system appended by the SIP port. Check
System: VoIP: Setup: SIP Ports: SIP UDP Port (1801-01) to see which port you
should use. For example, 172.16.3.3:5060 speci es the DSX system at IP address
172.16.3.3 and uses SIP port 5060.
This is the frequency with which the AP20 Access Point reregisters with the
DSX system. Leave this value at default (300 seconds).
Use this option to select the method the AP20 Access Point uses to convey
DTMF information to the DSX system. Choose RFC 2833.
Only G711U should be available. Delete all other codecs from the list. You'll
need to create a unique Pro le in DSX that only offers G.711 @ 20ms. See Step
5. Program the DSX on page 8 in the Installation Checklist for more.
These controls modify the Codec Priority list. Make sure the list only offers
G711U.
Use this option to add an additional server (DSX system). Adding a server leaves
the existing server unchanged. An AP20 Access Point can be assigned to only
one DSX system.
Click this option to remove (delete) the server on-screen. Removing a server
also deletes all the ML440 extensions associated with it.
