<b>Cost-effective, High-performance PoE VoIP Phone</b>
To build high-performance VoIP communications at a low cost, PLANET now introduces the latest member of its IP Phone family, the VIP-2020PT enterprise-class 2-Line PoE IP Phone. It complies with IEEE 802.3af PoE interface for flexible deployment. The VIP-2020PT makes it simple for the enterprise featuring voice and data system or expanding voice system to new locations. It helps the company to save money on long distance calls; for example, the remote workers can dial in through a Unified VoIP Communication System just like an extension call but no long distance call charge would occur. The VIP-2020PT also allows call to be transferred to anyone at any location within the voice system, which enables the enterprise to communicate more effectively and is helpful to streamline business processes.
<b>High Quality HD Voice over IP</b>
The VIP-2020PT delivers HD voice (High-Definition Voice) which is the next generation of voice quality for telephony audio, making the quality of voice better than that (toll quality) of the standard digital telephony and even close to that of a room conversation. HD voice is transmitted in the audio frequency range of 50 Hz to 7 kHz or higher over telephone lines, resulting in higher quality voice and clearer communication.
<b>Standard Compliance</b>
The VIP-2020PT supports Session Initiation Protocol 2.0 (RFC 3261) for easy integration with general voice over IP system. The VIP-2020PT is able to broadly interoperate with equipment provided by VoIP infrastructure providers, thus enabling them to provide their customers with better multi-media exchange services.
<b>Enhanced, Full-Featured Business IP Phone</b>
The VIP-2020PT is a full-featured enhanced business IP Phone that addresses the communication needs of the enterprises. It provides 2 voice lines and dual 10/100Mbps Ethernet. Furthermore, the VIP-2020PT delivers user-friendly design containing a 128×48 Graphic LCD with white backlight, 2 Line keys and 4 soft keys. It supports 5 extension consoles with each consisting of 26 keys.
The VIP-2020PT supports all kinds of SIP based phone features including Call Waiting, Auto Answer, Music on Hold, Caller ID and Call Waiting ID, 3-way Conferencing, Call Hold, Call Forwarding, Black List, DTMF Relay, In-Band, Out-of-Band (RFC 2833) and SIP INFO, among others. Besides office use, the VIP-2020PT is also the ideal solution for VoIP service offered by Internet Telephony Service Provider (ITSP).
<b>Secure, High-Quality VoIP Communication</b>
The VIP-2020PT can effortlessly deliver secured toll voice quality by utilizing cutting-edge 802.1p QoS (Quality of Service), 802.1Q VLAN tagging, and IP TOS (Type of Service) technology. Using voice and data VLAN can easily separate the data and voice, thus maintaining the best quality.
<b>Professional Application</b>
The VIP-2020PT supports Busy Lamp Field (BLF) function that, via the lights on the phone, enables users to easily identify the status of other phones which are connected to the same IP PBX, such as busy, idle, ringing, etc. The connected IP PBX must also support BLF feature. The BLF function is helpful for a receptionist on the front desk to route all incoming calls smoothly.
