To allow calls to be routed from the Lotus Sametime Unified Telephony to the correct gateway additional Endpoints (EP) need to be created for each SIP Gateway (PSTN (Public Switched Telephone Network) gateway).
Gateways may dynamically register however most are statically registered. Only the static registration scenario is described.
An EP should be created as statically registered with the IP address/port of the interface created on the core side of the SBC for the gateway. The SBC should have its own configuration for associating the SBC core interface to the SBC's peer network interface for the gateway. The EP should be configured with an alias name corresponding to the User Name configured in the gateway. The SIP Proxy and Route via Proxy attributes are not required for this EP.
