1. A method for providing telephone application services using a managed VOIP network, where voice data transmitted over the network is codified in a native VOIP format, said method comprising the acts of:
- providing a plurality of channels for handling incoming telephone calls and a shared memory, accessible to all channels, storing response voice data in native VOIP format;
providing an I/O thread for each channel for managing all I/O, with I/O thread performing the following acts;
while playing a message, giving higher priority to data transmission than to data reception; and
while recording a message, giving higher priority to data reception than to data transmission;
receiving a first incoming telephone call, including a first plurality of received EP packets encapsulating voice data in native format, from a service requestor over the managed VOIP network;
setting up a connection between the incoming telephone call and a first one of said channels for handling the incoming telephone call;
identifying a requested service;
accessing response voice data, stored in the native VOIP format in said shared memory, responsive to the requested service;
encapsulating said response voice data in a second plurality of response IP packets; and
sending said second plurality of response IP packets over said managed VOIP network to the service requestor.

Abstract
An integrated VoIP unified message processing system includes a voice platform that processes data in native VoIP format. There is no use of hardware telephone interface cards (TICs) or software transcoding to transform data to PCM or other formats. Cost reductions are achieved by the elimination of expensive dedicated hardware and scalability is achieved by obviating the need for software transcoding.

7. A method for providing telephone application services using a managed VOIP network, where voice data transmitted over the network is codified in a native VOIP format, said method comprising the acts of:
-
providing a plurality of channels for handling incoming telephone calls and a shared memory, accessible to all channels, storing response voice data in native VOIP format;
providing a plurality of message access servers for controlling access to shared memory;
receiving a first incoming telephone call, including a first plurality of received IP packets encapsulating voice data in native format, from a service requestor over the managed VOIP network;
setting up a connection between the incoming telephone call and a first one of said channels for handling the incoming telephone call;
identifying a requested service;
utilizing a service requestor ID to access a user database holding an association between the ID and a home MAS for accessing response voice data for the service requestor, wherein the accessed response voice data is stored in the native VOIP format in said shared memory;
encapsulating said response voice data in a second plurality of response IP packets.
