Polycom 331 POE

product picture Introducing the SoundPoint IP 331 and 321 two-line SIP phones that deliver superb sound quality as well as a wide range of supported business telephony features. The SoundPoint IP 331 phone, with its dual-port 10/100 Ethernet switch for LAN and PC connection, presents a cost-effective solution for cubicle workers as well as call center operators who use a “hard” phone in conjunction with a “soft” client running on the PC. The SoundPoint IP 321 phone has a single 10/100 Ethernet port, therefore its application targets include common areas, such as lobbies, hallways, and break rooms, as well as various wall-mounted deployments.



Additional Information

Superb Sound Quality

The SoundPoint IP 331 and 321 phones from Executive Telephony feature a full-duplex IEEE 1329 Type 1-compliant speakerphone with Polycom's legendary Acoustic Clarity Technology that delivers excellent sound quality and enables noise-free and echo-free conversations that are as natural as being there.

Enterprise-Grade Feature Set

The SoundPoint IP 331 and 321 phones deliver through an intuitive user interface a full feature set encompassing both traditional business telephony features such as call hold, park, pick-up, transfer, and three-way local conferencing, and more advanced capabilities such as shared call/bridged line appearance, support of XHTML applications, and distinctive call treatment.

Efficient Installation and Provisioning

The SoundPoint IP 331 and 321 phones are engineered to make installation, configuration, and upgrades as simple and efficient as possible. The phones’ standard base stand can be reversed to become a wall mount, eliminating the need for a separate accessory. Built-in IEEE 802.3af PoE circuitry and a dual-port Ethernet
switch (SoundPoint IP 331 phone only) enable flexible deployment options and savings on cabling expenses. The SoundPoint IP 331 and 321 phones support remote, zero-touch provisioning and upgrade from a variety of servers, including FTP, TFTP, HTTP, or HTTPS. To ensure reliable, uninterrupted performance, the phones support boot and call server redundancy.

Broad Interoperability

The SoundPoint IP 331 and 321 phones have been tested and certified to deliver comprehensive interoperability and extensive feature support with leading SIP-based call control platforms by BroadSoft, Sylantro, Interactive Intelligence/Vonexus, Digium, and other Polycom Technology and Interoperability Partners2. The phones also interoperate with Microsoft® Live Communications Server (LCS) 2005 for telephony and presence. This broad interoperability offers Polycom customers a choice of supported standards-based call server solutions with which the phones can be deployed.
