A method of processing multi-media service requests received at a multi-media services provider computer system, including a processor coupled to a media gateway controller and to a media server. The method includes receiving a message from a SIP INVITE-enabled communication device at the media gateway controller. The message is processed at the media gateway controller and at the processor for generating an instruction message with unique indicators, which is communicated to the media server in a SIP INVITE format. The media server processes the instruction message to provide media services and collect user-information from the communication device. The media server processes the user-information and generates a first message in an HTTP form POST format with unique indicators, which includes the user-information and which can be processed at the processor. In this manner, the multi-media services provider computer system is compatible with the SIP INVITE-enabled device.
