The setting parameters relating to the SIP are as follows:
A) Telephone Number
This parameter is used to set the telephone number of the line. The telephone
number is a unique ID when the gateway serves as the caller.
B) 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.
C) SIP Registration Server
The SIP registration server is a server used by the gateway to register the
account. This parameter is used to set the IP address or domain name of the SIP
login server. If the SIP registration server uses a 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.
D) 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 .

C. Jitter Delay Processing Mode
This parameter is used to specify the algorithm model of the jitter delay buffer.
The “Adaptive” mode should be set. Other modes are only used for tests and
should not be set in actual applications.
D. Media QoS
Quality of Service (QoS) is a network’s capacity to provide priority services,
including the special bandwidth, jitter control and delay (used for real-time and
interactive traffic), and improvement of the packet loss ratio. This parameter is
used to mark the specified QoS label for the voice packet to increase the network
service quality.
Note: For details about media encryption and media NAT penetration, refer to
This parameter is used to modify the compression coding according to the
requirements of the service provider.
If a compression coding is ticked, it indicates that the compression coding is
available. The UP and DOWN are used to adjust the priority of the selected voice
compression coding.
