The advance setting of the SIP involves the signaling and media. Users can set
according to their special requirements.
Select SIP Menu > Advance Setting/Media.
A. Signaling Port (SIP Local Port)
The SIP local port is the local UDP port. It is used for communications between
the SIP agent and the SIP proxy server as well as other SIP managers.
B. NAT Hold

signaling communication. The unit of the parameter is m.

B) Gateway Prefix
The gateway prefix enables the connection of call s through a particular line. It
can match the first digit only. You can set a gateway prefix for multiple lines.
When you set a gateway prefix for multiple lines, the call s that have the same
gateway prefix will select the line set with this gateway prefix. For example, the
gateway prefix is 1. When the user dials 10086, the call will be connected by the
line with the gateway prefix 1. When the user dials 075588290211, the system
detects whether the line with gateway prefix 0 exists. If exists, the call will be
connected. Otherwise, the call will be released.
Note: When you set the GSM VOIP Gateway by lines, the gateway prefix must be
set. Otherwise, the call will not be connected.
C) SIP Proxy Server
This parameter is used to set the address of the SIP proxy server. If the SIP
proxy server uses the special port (other than the SIP default port 5060), you can
add the detailed port number at the end of the IP address or domain name of the
proxy server. For example, 192.168.2.26:3000 or hy.con.com:3000.
D) SIP Registration Server
The SIP login server is a server that the gateway registers the account. This
parameter is used to set the IP address or domain name of the SIP registration
server. If the SIP registration server uses the special port (other than the SIP
default port 5060), you can add the detailed port number at the end of the IP
address or domain name of the registration server. For example,
192.168.2.26:3000 or hy.con.com:3000.
E) Outbound Proxy
The outbound proxy is mainly used in the scenarios where the firewall or NAT
exists, so that the signaling and media stream can penetrate the firewall.
F) Homing Domain
This parameter is used for the domain management host of the SIP (a host that
provides the SIP service).
G) Authentication ID
This parameter is used to set the authentication account when the gateway logs
into the SIP proxy server.
