SIP entities in the network are categorized as either subscribers or endpoints. A SIP subscriber has a subscriber ID (phone number) and requires a subscriber license.
A SIP endpoint has a name, rather than a phone number, and does not require a license. Endpoints are typically gateways or peer SIP servers in the network. Subscriber features are generally not provided to SIP endpoints.
Comparable to the endpoint profile, the administrator can create an endpoint under the global numbering plan, or under a numbering plan of a business group that has been created solely to contain the gateways to the PSTN, and that does not include any users.
The endpoint definition must have:
A name (just an alphanumeric string).Note:
Type – indicates whether the device will be statically or dynamically registered. Most gateways and peer servers are statically registered (they do not send REGISTER messages to Lotus Sametime Unified Telephony).
An IP address or FQDN (for example, server31.Lotus.com), if the device is to be statically registered.
If dynamic registration is selected, the user cannot enter an IP addressor FQDN. These values will be determined when the device registers.
Authorization type (by endpoint or by subscriber). The former is most common for gateways, meaning that the endpoint is pre authorized to make and receive calls. If the endpoint option is selected, the user must identify an endpoint profile, which was previously created.
Endpoint profile name (see above) selected from the list of already defined profiles.
The name or alias for the gateway. The alias is the name string by which the gateway will register with the Lotus Sametime Unified Telephony (if it is dynamically registered) and the name by which the gateway will be known in the SIP registrar database.
A SIP gateway has completely different feature capabilities from a SIP subscriber endpoint. However, it is possible to use a SIP telephone or soft client as a gateway simulator, to test routing results, before the real gateway is installed and available. A SIP gateway (typically) behaves much like a featureless SIP phone with an unusually high call handling capacity.
A endpoint defined with an endpoint profile cannot have subscriber features (suchas CSTA or call forwarding) provisioned.
