6-34
Description
This command sets how switching between primary & secondary SIP servers is managed
by the gateway.
If PERMANENT is set, then once the current server is noted as failed, all subsequent
server requests will be routed to the alternate server. The alternate server will con-
tinue to be used until such time as it fails, at which point all subsequent server
requests will be routed to the original server.
If DNS-BASED is set, then upon primary server failure all future server requests for
this particular dialog will be routed to the secondary server. Any subsequent new
dialogs created on the gateway will always try to contact the primary server first.
The default value is permanent.

--> voip sip protocol set server-redundancy dns-based

authentication fails, or when no responses are received
from the server (link fails).
LINK-FAILURE-ONLY
Switching between the provisioned servers happens only
when no responses are received from the current server
(link fails). A failed authentication does not cause a server
switch.
