"List price" is the suggested retail price provided to us by our vendors. We make no representation that a substantial number of these products have been sold or offered for sale at the list price. Actual retail prices in your area may be substantially different. Since we sell products on a national basis, it is not possible to know if our merchandise is sold at list price in any particular location or at any particular time. "You Save" reflects the difference between our price and the vendor provided list price shown on our sites. Since the list price may be different than the actual retail prices in your area, you may not actually realize a savings of this amount.

Manufacturers sometimes ask that retailers not display a price if it drops below a certain amount. The "Click here to see Lowest Price" message indicates that the price of the item is so low that the manufacturer requested that it not be advertised (that is, displayed). In a brick-and-mortar store, you would probably have to ask a salesperson what the price of the product is. At eCOST, by clicking on "Click here to see Lowest Price" you are essentially asking to see the price, at which point we show it to you.

All phones support digital labeling, PoE, four-way navigation controls, and are available with high-resolution backlit and color TFT displays.

In addition, they deliver rich, full body, wideband voice clarity with full-duplex speakerphones, as well as offer intuitive interfaces, Gigabit Ethernet support, and environmentally friendly power-save options. Ideal for common areas and everyday desktop business use, the phones are the perfect solution for knowledge workers, departmental administrators, and teleconference participants with intensive communication requirements. Optional accessories include wall mounts, AC power adapters, and deskstands.


  • Nine definable ring tones --- offer a choice of ring tones, which are used when alerting users of new incoming calls and can be configured via the Web provisioning interface; provides customers with a choice to further personalize the phone to meet their own needs

  • Browser-based management --- Web-based management on the VCX server eases configuration tasks and makes advanced features easier to master; customization capabilities allow users to accomplish a variety of setup procedures themselves

  • Support for 10 different languages --- all 350x series IP phones have user interface localization capabilities with the support of the following interface languages: Chinese (Simplified), Dutch, English (US), French (European), German, Italian, Korean, Portuguese (Brazilian), Spanish (Latin), and Russian

  • VCX IP phone license support --- all 350x series IP phones require a software keycode license (sold separately) to activate; 350x phones will work with legacy VCX 7.x , 8.x, and 9.0 IP phone licenses, along with 9.5+ IP phone licenses, as long as VCX system is running software version 9.5 and later; all IP phone licenses are managed from the VCX administrator Web provisioning interface

  • Country-specific tones --- VCX Connect solution allows administrators and users to configure phones for a certain country, which specifies the tones used by the phone; the country configuration for the phone is on a per-user basis via Web provisioning
  • Gigabit Ethernet connectivity --- to reduce cabling costs and eliminate the need for a standalone switch port, 350x series IP phone models offer two switched Gigabit Ethernet ports, except for the 3500B model, which supports 10/100 connectivity; the second port is used as a PC pass-through port that supports handling and passing of IEEE 802.1x EAP packets; this helps ensure that the desktop phone is an integral part of a high-performance network and is ready for future connectivity needs

  • Optional connectivity accessories --- include ergonomically designed wall mounts that fit the form factor of the 350x phone design, AC power adapters, and replacement phone stands

  • IEEE 802.3af Power over Ethernet (PoE) support --- all 350x series IP phones support IEEE 802.3af Power over Ethernet (PoE) and help reduce the total cost of ownership

  • Green technology --- all 350x series IP phones support configurable energy conservation options that include both a screen-save capability and a deep sleep power-save mode; user- and administrator-configurable power-save options reduce energy use by up to 50% relative to peak usage requirements

  • Energy Star 2.0 power adapters --- optional 350x series IP phone power adapters are designed to be Energy Star 2.0 compliant to make them more efficient than conventional adapters
Ease of use
  • Context-sensitive soft keys --- 3503 model phones have five interactive and context-sensitive soft keys, while the remaining models have four, facilitating efficient management of the most demanding communication needs; this enables easy access to the user directory, call logs, speed dials, and feature lists from the LCD soft keys; all phones use either icon- or text-driven menu selections for universal understanding of feature options
  • A phone portfolio for all business needs --- 350x series phones offer a comprehensive suite of devices designed for the most demanding and varied range of work environments and users; easy-to-use features make these phones ideal for common areas and everyday desktop business use, as well as for knowledge workers, departmental administrators, and teleconference participants with intensive communication requirements

  • Customizable system-wide background image --- options such as customizable background images on the 3503 IP phone provide enterprise administrators with the flexibility to upload a company-wide corporate image

  • Three-page button-mapping features --- one-touch call handling, enabled by programmable feature buttons accessible by a unique three-page scrolling feature on the 3502 and 3503 IP phones, provides the scalability and flexibility to map three times the number of features as available buttons.

  • Flexible date and time display --- allows administrators or users to configure date and time displays on the phones using the Web provisioning interface, which provides displays based on user preference or location preference
Technical features
  • Phone mobility and roaming --- allows system administrator to determine whether end users can move their stations; phones/soft clients can be locked to a physical switch port (using MAC address) or to a specific IP subnet; end users can move their phones to any location that has IP access to the user's telephony server, regardless of geographic location; hot desking is supported with VCX when logging into a different VCX region or branch that is configured for Global Directory
  • Full-duplex speaker phones --- all 350x series IP phones feature full-duplex speakers, which provide a more superb "real" communication experience, even with the entry-level phones
