The small business solution for an active, on-the-go workplace.


Built specifically for your small business or restaurant, answering and transferring calls is easy with the M-KLE Cordless 4-Line Series. The desk phones and cordless handsets feature “key system emulation” (KLE) for improved call handling — making it easy to see incoming calls, hold calls, and pick up a call on hold from the handset with a simple press of a line button. The key-line mode of operation means someone can place a call on hold with one button, then retrieve the call from another device with one-touch. No crazy Call Parks or star-codes, just press hold, the caller hears hold music, and the key-line light blinks on every phone.

Easy deployment: Only the base station control unit requires configuration by us. After set-up, you can add up to a combination of 10 cordless handsets or cordless desk phones any time your business grows.  And because its all wireless — using DECT (not Wi-Fi) — you’ll be using your new phones in no time!

Improved call handling: It’s easy to see incoming calls, hold calls, and pick up a call on hold from the handset with a simple press of a button. The series can manage 6 calls on the handset and features dual mode operation: key system or multi-key line appearance.

Long, wireless range: DECT 6.0 technology allows people to move and stay connected with up to 500 feet of range, so employees can go as mobile as they need in a bustling business.  No need to rewire the entire office, just connect the control unit then set your new phones anywhere in your business at any electrical outlet.

What Our Customers Say

Don't just take our word for it. Let our clients share their own success stories!

"When a patient will call our Belleville office rather than our 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

"I have worked with Matt and his firm for a number of years. His service and attention to detail are some of the best I have experienced. He is always open to ideas and is very willing to act on good ideas. It is a pleasure working with him and his company. Highly recommended."
