Abstract:
1. A method comprising: in response to receiving at an electronic telephone number mapping server an electronic telephone number mapping query request message identifying a called first user endpoint called by an originating device from a call server associated with the originating device, determining at the electronic telephone number mapping server whether the called first user endpoint is subject to re-direction; determining, using a processor at the electronic telephone number mapping server, a second user endpoint when the called first user endpoint is subject to the redirection, the second user endpoint destination being different from the called first user endpoint; and sending an identifier associated with the second user endpoint from the electronic telephone number mapping server to the call server associated with the originating device when the called first user endpoint is subject to re-direction to thereby enable the call server to convey a communication session initiation message to the second user endpoint without triggering an end-point call feature at the called first user endpoint or at a terminating call server associated with the called first user endpoint.
