Outbound Proxy Server.
This is the IP address of the server that handles call control for the
ZIP4x4.
Backup Proxy Server.
This is the IP address of the backup proxy server. The ZIP4x4 will attempt
to switch to the backup proxy if the primary proxy server fails to operate..
Registrar Server.
This is the IP address of the registrar server. When this value is set, the ZIP 4x4
attempts to register with this server instead of the proxy.
RTP Start port.
The ZIP4x4 uses consecutively numbered RTP and RTCP port numbers (actually
UDP port numbers) for communication. RTP carries media and RTCP carries control information.
The default RTP start port is 1760. The first call appearance uses port 1760 to receive media and
port 1761 to receive RTCP control information. The second call appearance uses ports 1762 and
1763. The highest port in use is 1767. The RTP start port must always be an even number and
should not be set to the same value as the Receive Port or the Proxy Port.
Receive Port.
This is the TCP or UDP port number the phone uses to receive SIP messages. The
default value is 5060 and that is used if you leave this field blank.
Proxy Port.
