ABSTRACT:
An apparatus and method for providing dynamic Push To over Cellular, PoC, service options in a wireless communication network. Service options and terminal capabilities for PoC Clients (11, 15) are stored in the network, preferably in a PoC Server (13). A PoC Client (11) uses a SIP PUBLISH message (17) to set the actual status of the answering mode and any barring service, and, if automatic answering mode is set, also stores a list of codecs that the PoC Client (11) supports. When the PcC Client is called, the calling PoC Client (15) informs the Server (13) of supported codecs, and the Server selects a codec supported by both Clients, thus optimizing the connection.
