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 modules are registered per
gateway port, while FXO modules send a single registration message, where Username is
used instead of phone number in From/To headers. The registration request is resent
according
'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.
