Voice over Internet Protocol Voice Quality of Service
Service providers considering the implementation of VoIP (Voice over Internet Protocol) need to be sure to prevent potential problems causing voice quality degradation. This requires monitoring the network to measure voice quality, as well as to predict voice quality under various network conditions. Preventing the degradation of voice quality involves four important steps:
Providing enough capacity in the network to handle voice calls
Properly choosing and implementing the best Call Admission Control capability of the Session Management/Call Session Control Function or gateway
Conducting a VoIP security audit
Implementing an effective voice quality monitoring program.
