Steadfast has been our Telephone provider for five years, and during those five years, I must say that we were very happy and satisfied with their service. If there was ever a problem that I did not understand, I'd quickly call and within minutes my phone was up and running. I was totally surprised when I explained a phone problem and it was fixed remotely. If there was a time things could not be fixed remotely, within minutes a technician would be there. All of their technicians were very professional, polite, and well mannered,and went out of their way to make sure that systems were up and running within no time.
Love you guys.
Ruth E.

"With the help of Steadfast’s's expertise we were able to network our numerous locations, allowing us to process calls between locations more effectively."
-Robert Shaloff, The Vinegar Factory

You have taken the time to to teach us how to use the system and you have been so patient. Steadfast Telecommunications has made what could have been a difficult transition smooth and seamless.

VoIP New York

Welcome to Steadfast Telecommunications! We have been providing some of the best telephone systems and VoIP New York has to offer since 1976. We are proud to install phone systems New York businesses can truly count on for increased efficiency, cutting–edge technology, and overall cost–efficient telecom solutions.

Phone Systems New York Businesses Can Trust

In an age where we practically cannot exist without the internet, VoIP technology has never been a more necessary part of good commerce practices. We pride ourselves on being more than just another VoIP NYC company looking to amass our client base. We aim to work one on one with each of our clients to make sure that they get the service they've come to trust, and at a price they can get excited about.

Simplified. Streamlined. Secure.

Providing top–notch business phone systems NYC companies have been trusting for more than thirty years means going above and beyond the status quo. We provide a hosted PBX New York businesses can rely on for a better experience, without having to pay for all the expensive extra hardware.

Our streamlined practices will help save you time, increase your efficiency, and keep your costs down. Sick of misdials or switching from desktop to phone what seems like every five seconds? With our VoIP systems, you won't have to. Link your Outlook to your phone, so you can click a number and it immediately dials. Have contacts stored on your phone system so a conversation is just a click away—and you won't have to worry about looking up addresses, memorizing a myriad of numbers, or fumbling through piles of papers.

We can provide you with a number that's localized to almost anywhere in the country, and even many locations abroad, so that your international clients can reach you without having to pay international rates. You can get an intelligent scheduling system for simple and complex call scheduling. The system can even screen with a "Do Not Call" list to automatically block calls from telemarketers, or any other phone–pests you don't want to waste your time with.

For even further convenience, we'll provide you with faxes converted straight to your email—and voicemails too! No longer will you have to have manage multiple inboxes—listen to voicemails right in your Outlook, faster than you can catch a cab outside Grand Central.

With the services we provide at Steadfast Telecom, we go above and beyond the other VoIP service providers New York has had to deal with. We provide you with superior service, and at a lower cost. We work hands on with our clients to make sure that they are getting the exact service that works best for their business. Whether it's a hosted PBX NYC can afford, or simply providing the streamlined business phone systems New York deserves, Steadfast is here for you.
