IP Softphone is Easy-to-Install Software
It turns any laptop or desktop PC into an extension of your KX-TDA, KX-TDE or KX-NS series phone system. With IP Softphone, all you need is a high-speed Internet connection to make and receive calls using a headset that plugs into your PC. And it doesn’t matter where in the world you are as long as you can connect to a local (LAN) or wide (WAN) area network over a VPN.
Ensures Excellent Voice Quality
The Panasonic IP Softphone converts digital voice into standard RTP*/IP packets, which are then transmitted over a TCP/IP network. The product facilitates Quality of Service by supporting VLAN tagging (802.1p/Q) to enable dedicated bandwidth to handle voice traffic. Furthermore, IP VPN tunnel can ensure that voice speech is encrypted so there is virtually no chance of eavesdropping as the voice packets travel over the Internet.
*RTP = Real Time Protocol
