DETERMINING QUALITY OF VOICE CALLS OVER A PACKET NETWORK |
摘要 |
<p>The present invention provides a method for managing a voice call over a packet switched network, in which the voice call is rerouted when voice quality is below a predetermined level. In particular, the voice quality is determined by calculating a parameter representing the voice quality based on information regarding codec, network delay and packet loss. Preferably, R-factor and MOS is calculated based on the information obtained from Cisco CDRs during the call session.</p> |
