Acoustic Fence™ Technology = Voice Clarity Excellence

Our Polycom VVX-series phones with Acoustic Fence™ technology keep business conversations free from extraneous noises and distractions typically surrounding most office (or home office) environments.  Exclusive to Polycom, they make this possible by using multiple microphones in the phone to automatically reducing background noises – co-workers’ chatter, loud machinery, or even barking dogs for example – and “cancel out” all soundwaves except the actual speaker’s voice.  The end result reduces and allows remote callers to hear and focus on the meeting at hand.


High Definition Sound

Polycom VVX deliver high definition sound like you’ve never heard before. Finally make “buzzing” and “scratchy” telephone calls a thing of the past!

Acoustic Fence™

The person on the other end of the phone call will clearly hear your voice – and only your voice – while Acoustic Fence automatically minimizes or eliminates background noise around.

iOS & Android Mobile App

Employees can work remotely, review call history, search the directory, or see if a colleague is available for a call — as easily as they do in the office.

Detailed Reporting

Know who is calling who, which employee is the most productive, and identify trends for discovering additional business opportunities.

Returned Call Connector

When a client calls back, their call can be automatically routed directly to the original extension that last dialed them. Never lose a potential sale again!

Call Monitor & Recording

Managers can silently listen in on active calls to monitor performance, jump-in to help, or optionally record calls automatically for review later.

Shared Phone Book

Easily manage one centralized phone book and share that directory of phone numbers automatically to all phones in your system — searchable by name, or company, or email address!

Meet Me Conference

Host multi-party conference calls, anytime you need. Determine if the call will be a webinar style or open group discussion, then send out the invites or have the phone system call them.

Call Queuing

Receive more calls than you can answer? With Phonewire, your callers can wait with music to be answered in order or offer them options to send their call to another phone or voicemail.

What Our Customers Are Saying

Don’t just take it from us, let our customers do the talking!

“When a patient accidentally calls the Belleville office instead of the Mt. Vernon location, instead of asking them to hang up and dial another number (hoping we don’t lose that new client), we can now just transfer them to the other office without their ever knowing the difference.”

Mary Barr

Periodontics of Southern Illinois

“Switchvox was built for a company just like ours who wants all the features and functionality of an Asterisk-driven system, but one that is preconfigured and packaged at a bundled price that is significantly more affordable than any of the big box brands.”

Mark Ratliff


“As a manager, I never had any way with the old system to know who was calling who, nor was I able to track any trends like what days we seemed to get the most phone traffic and what kind of calls they were.  Having these features help us make better staffing decisions and analyze our advertising effectiveness.”
