D-Link Systems, Inc. 22
SETUP → VOIP SETTINGS
Use DNS SRV: Check the box to use DNS SRV to connect to the SIP proxy server. Domain Name Server
(DNS) SRV helps clients connecting to the SIP proxy server with a specific domain and get back the IP
address of any available server.
DNS SRV Auto Prefix: Check the box to use _sip._udp.domain.com to query IP by default. The gateway
will use domain.com to query IP if un-ticked.
Proxy Fallback Interval: Enter the interval for the gateway querying the IP address of the main server if
the gateway has registered to the secondary server.
SETUP → VOIP SETTINGS
Enable Support of SIP Proxy Server / Soft Switch: Check the box to register the gateway with SIP proxy
server or soft switch. The gateway is registered with SIP Proxy 2 if all lines have failed to register with SIP
Proxy 1. SIP Proxy 2 will be a backup proxy if both SIP Proxy 1 and 2 are enabled.
Proxy Server IP/Domain: Enter the IP address or URL (Uniform Resource Locator) of SIP proxy server or
soft switch.
Proxy Server Port: Enter the SIP proxy server’s listening port for the SIP in this field. Leave this field to the
default if your VoIP Service Provider did not give you a server port number for SIP.
Proxy Server Realm: Enter the realm for SIP proxy server. It is used for authentication in a SIP server. In
most cases, the gateway can automatically detect your SIP server realm. So you can leave this option
blank. However, if your SIP server requires you to use a specific realm you can manually enter it here.
