DNS SRV Settings

y Use DNS SRV: The gateway asks for the related IP address of SIP Server from the records of DNS

SRV. DNS SRV uses several servers for a single domain for SIP proxy, to move services from host to

host and design some hosts as primary servers (the highest priority) for a service and others as

backups. If the primary server is not reachable, the gateway will go for backup server, and so forth…

y DNS SRV Auto Prefix: This option tells the gateway to send packet with service type when using DNS

SRV.

y Proxy Fallback Interval: Set the preferred Proxy Fallback Interval. After the time expires, the gateway

gets back for registration with the primary server.

Enable Support of SIP Proxy Server / Soft Switch

y Enable Support of SIP Proxy Server / Soft Switch: Enable the functions to inter-work with Proxy

Server / Soft Switch. When SIP Proxy 1 and 2 are enabled, the system will register to SIP Proxy 2 after

all lines have failed to register to SIP Proxy 1. SIP Proxy 2 is a backup system..
