VP-15 is perfectly suitable for companies with high requirements to the voice data transmission quality, reliability and usability.

High quality of sound 
The high performance of VP-15 phones is provided by the hardware based on advanced Realtek chip that allows to reach high data processing rates. The support for all the main audio codecs used in VoIP networks (G.711, G.723, G.726, G.729), echo cancellation, Silence Detector, Comfort Noise Generator, DTMF signals reception and generation as well as traffic prioritization (QoS) ensures high quality of voice data. 

In case of main Softswitch connection failure, VP-15 is switched automatically to a redundant SIP server with main server state control.
