A Push-to-X over Cellular (PoC) server ( 351 ) receives a server registration message ( 301 ) for a first called device from a second server. The PoC server ( 351 ) receives a PoC invitation message ( 310 ) with PoC preferences and a message ( 313 ) from an originating device ( 311 ). The PoC preferences determine what device to call first (e.g., a mobile device 315, 317 ) and how many hops the call can be forwarded (e.g., to a voicemail server) if the first-attempted device is not available, before discontinuing the connection. If a trigger, such as time elapsed, occurs for the first-attempted device ( 350 ) and the PoC preferences permit, the PoC server ( 351 ) sends an invitation message ( 360 ) to the second server ( 391 ). If the second server ( 391 ) is a recording server, the invitation message ( 360 ) includes a message ( 363 ) from the originating device that is compatible with the capabilities of the recording server ( 391 ).
