ALGO

Keep-alive Method

If Double CRLF is selected the 8188 will send a packet every 30
seconds (unless changed) to maintain connection with the SIP Server
if behind NAT.

Different Ports for Extensions

Enable the feature for certain proxies such as Cisco Communication
Manager 7, to send ring and page SIP requests through different port
numbers.

Server Redundancy Feature

Two secondary SIP servers may be configured. The 8188 SIP Ceiling
Speaker will attempt to register with the primary server but switch to
a secondary server when necessary. The configuration allows re-
registration to the primary server upon availability or to stay with a
server until unresponsive.
If Server Redundancy is selected the web page will expand as shown
below.

Backup Server #1

If primary server is unreachable the 8188 SIP Ceiling Speaker will
attempt to register with the backup servers. If enabled, the 8188 will
always attempt to register with the highest priority server.

Backup Server #2

If backup server #1 is unreachable the 8188 SIP Ceiling Speaker will
attempt to register with the 2nd backup server. If enabled, the 8188
will always attempt to register with the highest priority server.

Polling Intervals (seconds)

Time period between sending monitoring packets to each server.
Non-active servers are always polled, and active server may
optionally be polled (see below).
