17. [ddns] command
This function is for Dynamic Domain Name Server service. Once user register to
one DDNS server, he can specify domain name for the SIP Phone. When SIP Phone
reboot, it will automatically update it’s IP address to DDNS server. In this way, even SIP
Phone is using dynamic IP address, other endpoint can locate this SIP Phone by its
domain name.
1. -print: display DDNS overall information and configuration.
2. –enable: to enable/disable DDNS function.(ddns –enable 0/1, 0 for disable and 1
for enable).
3. -server: to set IP address of DDNS login server. (Now only one DDNS server is
available---www.dyndns.org)
4. -hostname: to set the registered Domain Name of SIP Phone. (Ex.
ddns –lp001.ddns.org)
5. –id: to set login ID of registered account to log in DDNS server.
6. –passwd: to set password of registered account to log in DDNS server.
7. –checkip: to enable/disable check IP function. If SIP Phone is behind IP sharing,
when this function is enabled, SIP Phone will check it’s public IP address by asking
IP address check server and send to DDNS server to update DDNS data. If this
function is disabled, when SIP Phone is behind IP sharing, it will send it’s private IP
address to DDNS server.
8. –checkipsrv1/2: to set IP address of primary and secondary IP address check
server.
9. -delay: to set the update interval time. SIP Phone will re-update its IP address in
this time. (ddns –delay 1-59m/1-24h , m means minute, h means hour)
10. –force: to force to execute DDNS update. Once user enters this command, SIP
Phone will update DDNS data immediately. (ddns –force “IP address of SIP
Phone”)
Note:
1. For now we only support DDNS server as www.dyndns.org.
2. User must register to DDNS server first, and specify user name and password in ddns
-id and ddns –passwd.
3. The default IP address of DDNS login server is member.dyndns.org.
4. User has to specify domain name applied for SIP Phone in ddns –hostname.
5. The default IP address of check IP server in is checkip.dyndns.org.
