6. In the 'SAS Proxy Set' field, enter the Proxy Set used for SAS. The SAS Proxy Set
must be defined only for the following SAS modes:
•
Outbound mode: In SAS normal state, SAS forwards REGISTER and INVITE
messages received from the UAs to the proxy servers defined in this Proxy Set.
•
Redundant mode and only if UAs don't support homing: SAS sends keep-
alive messages to this proxy and if it detects that the proxy connection has
resumed, it ignores the REGISTER messages received from the UAs, forcing
them to send their messages directly to the proxy.
If you define a SAS Proxy Set ID, you must configure the Proxy Set as described in
Step 8 below.
7. Click Submit to apply your settings.
