domain name provided by VoIP service provider. (For example:
sip.mycompany.com, IPv4: 192.168.5.170, or IPv6: fe80::20b:82ff:fe75:211d). This
is the primary SIP server used to send/receive SIP messages from/to HT818.

or domain name provided by VoIP service provider. (For example:
sip.mycompany.com, IPv4: 192.168.5.170, or IPv6 fe80::20b:82ff:fe75:211d:). This

Used by HT818 for firewall or NAT penetration in different network environments.
If symmetric NAT is detected, STUN will not work and only outbound proxy can
correct the problem.

registration fails. (For example: proxy.myprovider.com, or IP address, if any:
IPv4: 192.168.5.170/ IPv6: fe80::20b:82ff:fe75:211d). By default, this field is left
empty.
Prefer Primary
Outbound Proxy
If the user configures this option to “Yes”, when registration expires, the device will
re-register via primary outbound proxy. By default, this option is disabled.
