         2 . The computer of  claim 1 , wherein the plurality of instructions further cause the computer to establish a VoIP offload engine in the sequestered partition. 
     
     
         3 . The computer of  claim 2 , wherein to establish a VoIP offload engine comprises to establish a VoIP offload engine to perform all VoIP functions of the computer. 
     
     
         4 . The computer of  claim 1 , wherein the plurality of instructions further cause the computer to establish an Inter-Partition Bridge (IPB) to enable communications between the main partition and the sequestered partition. 
     
     
         5 . The computer platform of  claim 4 , wherein the plurality of instructions further cause the computer to establish IPB routing to enable use of components within the sequestered partition by the main partition. 
     
     
         6 .

         7 . The computer of  claim 6 , wherein the virtual machine includes the VoIP engine. 
     
     
         8 . The computer of  claim 6 , wherein the virtual machine monitor includes the VoIP engine. 
     
     
         9 . The computer of  claim 1 , wherein the main partition in unaware of the existence of the sequestered partition. 
     
     
         10 . The computer of  claim 1 , further comprising a third NIC separate from the first and second NICs, the third NIC being dedicated to the main partition. 
     
     
         11 . A method for Voice over Internet Protocol (VoIP) processing on a computer, the method comprising:
 establishing a main partition to perform multiple functions apart and distinct from VoIP processing, the main partition having one or more core processors;   establishing a sequestered partition dedicated to performing all VoIP processing of the computer, the sequestered partition having one or more core processors;   executing a controlled, real-time operating system in the sequestered partition, the controlled, real-time operating system being solely dedicated to executing VoIP applications; and   establishing a VoIP offload engine in the sequestered partition,   wherein the main partition is unaware of the existence of the sequestered partition and all VoIP processing performed on the computer is performed by the VoIP offload engine.   
     
     
         12 . The method of  claim 11 , further comprising:
 determining whether the VoIP offload engine is receiving VoIP activity, and   establishing a high frequency polling of transactional VoIP packets to permit real-time disbursement of data in response to the VoIP offload engine receiving VoIP activity.   
     
     
         13 . The method of  claim 12 , further comprising:
 determining whether an output VoIP call is being initiated; and   establishing a variety of Internet Control Message Protocol (ICMP) echo messages to determine which gateway route has the fastest access to a target caller and establishing a streaming connection to the target caller using a VoIP protocol in response to the output VoIP call being initiated.   
     
     
         14 . The method of  claim 12 , further comprising:
 determining whether an inbound VoIP call is being initiated; and   transporting VoIP data using a digitization standard in response to the inbound VoIP call being initiated.   
     
     
         15 . The method of  claim 14 , wherein the digitization standard comprises one of G.711 and G.729 digitization standards. 
     
     
         16 . An article comprising: a tangible, non-transitory storage medium having a plurality of machine accessible instructions, wherein when the instructions are executed by a computer, the instructions provide for:
 establishing a main partition to perform multiple functions apart and distinct from VoIP processing, the main partition having one or more core processors;   establishing a sequestered partition dedicated to performing all VoIP processing of the computer, the sequestered partition having one or more core processors;   executing a controlled, real-time operating system in the sequestered partition, the controlled, real-time operating system being solely dedicated to executing VoIP applications; and   establishing a VoIP offload engine in the sequestered partition,   wherein the main partition is unaware of the existence of the sequestered partition and all VoIP processing performed on the computer is performed by the VoIP offload engine.   
     
     
         17 . The article of claim of  claim 16 , wherein the instruction further provide for:
 determining whether the VoIP offload engine is receiving VoIP activity, and   establishing a high frequency polling of transactional VoIP packets to permit real-time disbursement of data in response to the VoIP offload engine receiving VoIP activity.   
     
     
         18 . The method of  claim 17 , wherein the instruction further provide for:
 determining whether an output VoIP call is being initiated; and   establishing a variety of Internet Control Message Protocol (ICMP) echo messages to determine which gateway route has the fastest access to a target caller and establishing a streaming connection to the target caller using a VoIP protocol in response to the output VoIP call being initiated.
