The invitation message may be directed to a communication device. The invitation message may be inserted into a setup message used to set up the packet data channel and the setup message may be sent to a second node. The invitation message may be extracted from the setup message by the second node and forwarded to a third node. The setup message may be processed to establish the packet data channel.
