Unregister on Reboot* • When selected, the Loudspeaker Amplifier automatically unregisters
when it is rebooted.
• When not selected, the Loudspeaker Amplifier remains registered
when it is rebooted.
Buffer SIP Calls When this is enabled, SIP calls to the speaker will be stored in memory
and will play when either the call is terminated or the buffer is full. The
receive buffer is 2MB in size and this is equal to about four minutes of
ulaw encoded audio.
RTP Settings
RTP Port (even) Specify the port number used for the RTP stream after establishing a
SIP call. The RTP port has to be an even number between 0 and
65534. This port can be programmed for people who are not working
on a local LAN, but who want to have outside access. Instead of RTP
port being a random port, it will be set up so that only two ports can be
opened in a firewall.
Note: The RTP port number has to be an even number because the
control port is always one port number higher. Therefore, audio will go
through the port number that you enter into the RTP port field, but the
RTP control signals will go through a port that is one number higher
than the RTP port field.

Note: You need to reboot for changes to take effect.
