3.6.5 Server Redundancy

The phone can be configured with multiple SIP servers, one primary and one or more
backup. The phone will switch to a backup server when the current primary server
fails. Backup server configuration can be static or can use advanced DNS methods. In
the case of static server lists, when a server registration fails, registration will be
attempted on another server. If the phone is not registered to the first server in the list
when registration fails, it will start by trying to register to the first server. When mak-
ing a new call, if the INVITE fails, the other servers in the list will be tried one by one
for routing signaling until the last server is tried.
Definition of signaling failure (registration or start of call):
If TCP is used: The signaling fails if the connection fails or the Send fails.
If UDP is used: The signaling fails if ICMP is detected or if the signal times out. If
the signaling has been attempted via all servers in the list and this is the last server then
the signaling fails after the complete UDP timeout defined in RFC 3261. If it is not the
last server in the list, the maximum number of retries using the configurable retry tim-
eout is used. For more information, see 4.6.2.1.2 Server <server/> on page 114 and
4.6.3.1 Registration <reg/> on page 121.
