8.11 Proxy or Registrar Registration Example

The REGISTER message is sent to the Registrar’s IP address (if configured) or to the

Proxy’s IP address. The message is sent per gateway or per gateway endpoint according

to the ‘AuthenticationMode’ parameter. Usually the FXS gateways are registered per

gateway port, while FXO gateways send a single registration message, where Username is

used instead of phone number in From/To headers. 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%.

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 ‘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.
