Proxy or Registrar Registration Example

Below is an example of Proxy and Registrar Registration:
REGISTER sip:servername SIP/2.0
VIA: SIP/2.0/UDP 212.179.22.229;branch=z9hG4bRaC7AU234
From: <sip:GWRegistrationName@sipgatewayname>;tag=1c29347
To: <sip:GWRegistrationName@sipgatewayname>
Call-ID: 10453@212.179.22.229
Seq: 1 REGISTER
Expires: 3600
Contact: sip:GWRegistrationName@212.179.22.229
Content-Length: 0
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. This parameter is used only if
registration is per device. If the parameter is not defined, the parameter UserName is used
instead. If the registration is per endpoint, the endpoint phone number is used.
The 'sipgatewayname' parameter (defined in the ini file or Web interface) 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
'sipgatewayname' parameter can be overwritten by the TrunkGroupSettings_GatewayName
value if the TrunkGroupSettings_RegistrationMode is set to 'Per Endpoint'.

new destination of the forwarded call (FXS or FXO device).
•
When call forward is initiated, the device sends a SIP 302 response with
a contact that contains the phone number from the forward table and its
corresponding IP address from the routing table (or when a proxy is used,
the proxy's IP address).
•
For receiving call forward, the device handles SIP 3xx responses for
redirecting calls with a new contact.
