Description
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.
Enable/Disable the tone (beep) before each page.
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.
Click the Save button to save your configuration settings.
Note: You need to reboot for changes to take effect.
Click on the Reboot button to reboot the system.
