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.
