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.
REGISTER messages are sent to the Registrar’s IP address (if configured) or to the
Proxy’s IP address. A single message is sent once per gateway, or messages are sent per
B-channel according to the parameter ‘AuthenticationMode’. 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%.
If registration per B-channel is selected, on gateway startup, the gateway sends
REGISTER requests according to the maximum number of allowed SIP dialogs (configured
by the parameter NumberOfActiveDialogs). After each received response, the subsequent
REGISTER request is sent.
