Wired or Wi-Fi
With Grandstream, you can select wired or wireless phones — whichever best fits your needs and installation situation. As features are used the same on either, training is easy and consistent.
Room to Grow
Protect your investment with a system that grows as your business grows. Begin as small as 1 site with 2 lines and 2 phones, expandable to multiple sites with up to 1000 phones all working together.
Manage multiple calls easily with buttons and lights for each line — know who is calling, who is on a call, and who is on hold — at every desk or wall-mounted phone in the system.
Receive more calls than you can answer? With optional call queuing, Grandstream can answer and ask the caller to wait on hold or offer options to direct their own call to an extension or voicemail.
Meet Me Conference
Host multi-party conference calls, anytime you need it. Determine if the call will be a webinar style with only one speaker or an open group discussion, then e-mail out the invites!
Communicate by text from your PC and get instant answers from colleagues without ever asking your callers to hold or using intercom with the Wave app for smartphone or computer.
Best for Cordless
DECT wireless handset connectivity allows you to receive calls wherever you are on the premises. Also, switch easily between desk phones and portable devices during conversations.
There’s no need to have multiple contact numbers for people who also use a cell phone. Integrate cell phones with your communications system and use them like office extensions.
With its built-in web browser programming interface, you or our technicians can easily, and often remotely, make any programming changes whenever needed.
Call Recording & Storage
Optional call recording allows you to choose to push a button during a call to start recording when needed or have all calls automatically recorded.
Managers are able to silently listen in on active calls to monitor employee performance or jump-in to help someone new in training.
Click to Call
Integrate with Microsoft® Outlook® allowing users to easily dial contact phone numbers, receive incoming call pop-up alerts, drag-and-drop conference call management.

What Our Customers Discovered
Don't just take it from us, let our customers share their success story!
"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."
"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."
"In the 10 years that I have had the pleasure of working with Phonewire, I have seen the business grow and differentiate itself from the rest. Matt works closely with customers to find a solution for their needs. The commitment to his work and to his clients is a true testament to his success."
Frequently Asked Questions
What's the warranty?
With a 1-year limited warranty from Grandstream, you can focus on growing your business. If you decide to rent your phones from us, the warranty is extended during the entire rental period. Optionally, the warranty on purchased phones can be extended for a very small cost by request on the original purchase date. Ask us to include the Extended Warranty option in your proposal.
Can you install it for me?
Do these phones work with headsets?
Yes. You can easily connect a wired or wireless headset to any of these phones. Some phone models also provide built-in support for any standard Bluetooth wireless headset. Ask us to include the number of headsets you need to your proposal and let us know if you’d prefer wireless or wired.
Can I page through the phones?
Yes. Paging is supported to allow you to announce your one-way voice message to any group or all phones. And, optionally, Grandstream allows you to create a two-way paging group that turns on all microphones and speakers for instant hands-free answer-back to your group announcement.
Can I forward, answer, or transfer calls to a cell phone?
Yes. And when you use the optional Smartphone Mobile Phone App for Android or iPhone, you’ll have the ability to place the call on music-on-hold, transfer the call to any other user, send the caller to your voicemail (or someone else’s voicemail), or enable immediate call recording.
Is this system compatible with provider X?
A Grandstream solution can integrate with any telephone service provider that offers PSTN (or POTS) analog or PRI (digital) telephone lines, or you can choose to have us host the phone system solution as a service in the cloud. Contact us to discuss and if you have any questions.
What about regular maintenance and support?
Do you offer financing options?
Yes, we do offer financing through our select lenders. Our attractive financing options make Grandstream an easy to implement solution within consideration of your available budget. Our proposal/quote will typically include one financing suggestion, but please do not hesitate to express your interest in other financing options so we can explore which program would be the best fit for you.
