The "servername" string is defined according to the following rules:

•The "servername" is equal to "RegistrarName" if configured. The "RegistrarName" can be any string.

•Otherwise, the "servername" is equal to "RegistrarIP" (either FQDN or numerical IP address), if configured.

•Otherwise the "servername" is equal to "ProxyName" if configured. The "ProxyName" can be any string.

•Otherwise the "servername" is equal to "ProxyIP" (either FQDN or numerical IP address).

The parameter ‘GWRegistrationName’ can be any string. If the parameter is not defined, the parameter ‘UserName’ is used instead.

The "sipgatewayname" parameter (defined in the ini file or set from the Web browser), can be any string. Some Proxy servers require that the "sipgatewayname" (in Register messages) is set equal to the Registrar / Proxy IP address or to the Registrar / Proxy domain name.

The Register message is sent to the Registrar’s IP address (if configured) or to the Proxy’s IP address. The message is sent once per gateway. The registration request is resent according to the parameter ‘RegistrartionTimeDivider’. For example, if ‘RegistrationTimeDivider = 70’ (%) and Registration Expires time = 3600, the gateway resends its registration request after 3600 x 70% = 2520 sec. The default value of ‘RegistrartionTimeDivider’ is 50%.
