If an identity is added to a location-service which is bound to a context sip-gateway, the following procedure
takes place:
1. Determine if identity should be registered.
a. The location-service containing the identity must have at least one domain configured.
b. The identity must have a registration outbound face configured or inherited.
c. The register command must be set to “auto”.
2. Build the address of record to register. The name of the identity builds the user-part. The first domain con-
figured in the location-service builds the host-part.
3. Build the address of the registrar. The registrar configured in the registration outbound face is taken as
request-uri. If no registrar is configured the first domain configured in the location-service builds the
request-uri.
4. Build expire header. If a lifetime is configured in the registration outbound face an expire header with the
desired lifetime is added.
5. Build contact address to register. The spoofed-contact parameter of the sip-interface in the context sip-
gateway through which the REGISTER request is sent is set as contact address. If no spoofed-contact is
configured the ip-address and port of the sip-interface in the context sip-gateway through which the REG-
ISTER request is sent builds the contact address.
6. Send the REGISTER request.
If one of these steps has no result and fails, the registration fails. After a certain timeout (which is configurable
in the registration outbound face), the request is re-issued.
