4.3.1 Basic Settings
SRV mode: It needs opening when DNS server adopts SRV-type DNS analysis;
SRV domain: When it is the SRV-type DNS analysis, SRV domain name needs
to be configured. Domain name starts with _sip._udp. For example, if the
allocated domain name is sbc.chinamobile.com, the configured one will be
_sip._udp.sbc.chinamobile.com.
Explanations:
Primary server: It supports domain name or IP address form;
Primary server port: It defaults to be 5060, but to fill in practically;
Backup server: To fill in it as per the main server’s parameters;
This device can support backup server: if there is something wrong with the
primary server, it will automatically register into the backup server. (at this
time please open heartbeat switch).
If the primary/backup servers adopt domain name mode, please open DNS
configured under WAN port, and correctly fill in DNS address.
