1.6.1 VoIP Tandem Carrier
The Packet Voice Processor is designed for insertion within VoIP environments
where large inter-exchange carriers transport voice over diverse networks or
exchange voice traffic within a diverse set of LECs (Local Exchange Carriers) or
enterprises. In these environments, the VoIP Tandem Carrier must convert the signal
between different VoIP codec formats, measure voice quality to ensure compliance
with regulatory mandates or service level agreements, and enhance voice quality
even when transporting the signal over a managed packet network. VoIP
applications for a VoIP Tandem Carrier can be divided into voice services for LEC,
International, and Enterprises.
displays the placement of the Packet Voice Processor within a network
of VoIP Tandem Carriers, as well as how the VQA and IPR technologies would
improve the call.
