Abstract:
1. A method comprising: receiving, at a first node, a first request from a first telecommunications terminal for an address of a first party in a telecommunications network; transmitting, from the first node to a second node, a request for subscribing to a Session Initiation Protocol registration event package for the first party, wherein the transmitting of the request for subscribing is based on no mapping of any indicium of the first party to the address of the first party being present at the first node; receiving a notification from a third node, wherein the notification comprises an indication that the first party is registered and the address of the first party; populating a database at the first node with a mapping of a predetermined indicium of the first party to the address of the first party received as part of the notification; receiving, at the first node, a second request from a second telecommunications terminal, wherein the second request comprises the indicium of the first party; and forwarding the second request to the address of the first party, based on the mapping that is populated in the database, wherein the second node is bypassed.
