In a telecommunication system, providing to a recipient end point a caller identification (CID) from a calling end point, the calling end point including a default CID and at least one additional CID, the method includes receiving a call setup message from the calling end point, the call setup message including the additional CID, allocating a temporary end point for the call, from a pool of available end points, sending contact data for the allocated temporary end point to the calling end point, processing a first call received from the calling end point to the temporary end point, processing a second call to the recipient end point using the additional CID as the calling CID, and joining the first and second calls to generate a call from the calling end point to the recipient end point.
