<p>A technique for providing an announcement in a communications network includes setting up a first level communication session in a first network element of the network. A determination is then made that an announcement is to be played to the first network element. An identity of a second network element which is to play the announcement on the first communication session is then sent and after a second level communication session is set up, the second level communication channel parameters are modified in accordance with the transmitted identity. The second network element then plays the announcement to the first network element (Fig 8). The transmitted identity may include an IP address or a port number or TA. The communication session may include a PDP context. The first network element may include a Mobile Station.</p> |
