SIP Operation Manual
Each line registers to Proxy independently:
As there are various Proxy Server providers, according to RFC standard our company has
designed the gateway to be compatible with them. If any registration problem occurs, please
consult your Proxy Server Provider.
NOTE: When you register with a Proxy, dialing principles may vary with different Proxy Servers,
especially when dialing through a remote end FXO port. Please consult your Internet Telephony
Service Provider.
DNS SRV Settings
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…
DNS SRV Auto Prefix: This option tells the gateway to send packet with service type
when using DNS SRV.
Proxy Fallback Interval: Set the preferred Proxy Fallback Interval. After the time expires,
the gateway gets back for registration with the primary server.
NOTE: Be sure that your Internet Telephony Service Provider supports DNS SRV. If you fail to make a
call, please contact your Internet Telephony Service Provider.
