Included Features

  • auto attendant

    Unlike using a live operator, the auto attendant means that you’ll never miss an important customer service call or sales opportunity again. You can customize your virtual answering service to route calls to the appropriate department, extension, or voicemail inbox, even after regular office hours.

  • Conference call

    Speak with up to two people at the same time with our built-in conference call feature. If you need to speak with a larger group, you can use our conference bridge feature to host as many callers as you like.

  • voicemail-to-email

    Voicemail-to-email delivers voicemail directly to your email inbox. You can listen to your message any time, from any device. It also makes it easy to retrieve old messages when needed, and your voicemail box will never fill up.

  • music on-hold

    Keep callers informed and entertained with messages and music on hold. Answer frequently asked questions, announce new products and services, offer directions or operating hours… It’s up to you. You can change your music or message as often as you like. We make it easy.

  • hunt groups

    A Hunt Group is a set of users handling similar types of calls. An example of a group would be sales department or customer support. When someone calls in to speak with sales they would ring one number but the call can be answered by any number of users who are assigned to that particular group.

  • find/follow

    Never miss an important call again. The find/follow feature makes sure that you get your calls no matter where you are. Choose whether to route a call to your cell phone or to a colleague, or both. Setting up this feature is easy and you can change it as often as you like.

  • Phones are included

    Tierzero Hosted PBX service comes complete with Polycom VVX500 telephones. These high-quality phones offer HD quality sound and generously-sized touch-screens. VVX600 phones are available at additional cost and include a larger screen, more lines, and Bluetooth compatibility.

  • mobile app

    The Tierzero mobile app is fully integrated with our cloud hosted phone system. Make and receive calls, dial extensions, transfer calls and change phone settings from anywhere.

Hosted PBX FAQ

  • What is Hosted PBX?

    Old school business phone systems ran through a physical PBX (Private Branch eXchange) box inside an office location. Hosted PBX is the cloud-based virtual version of that same technology delivered over an Internet connection.

    ‘Hosted PBX’ is a telco term. Out in the real world, it’s called by many names such as business voice, business VoIP, business voice over Internet, broadband phone service, etc. Essentially, all those terms relate to the same underlying technology - which is Hosted PBX.  It boasts more than 40 advanced features such as auto attendant, conferencing, hunt groups, and music-on-hold.

  • Why Should I Use Hosted PBX?

    Hosted PBX is a total game-changer in business phone systems. It gives any business of any size access to enterprise-level voice capabilities, without the enterprise-level expense. Hands down, Hosted PBX is the most efficient and affordable business phone system on the market. And it’s here to stay. Hosted PBX is not some ‘trend’ that will age out and need to be replaced by the next ‘new’ thing. It’s a future-proof software-driven technology that upgrades seamlessly with each new iteration and brings enhancements online with a simple click to download. 

  • What Does Hosted PBX Cost?

    Amazingly, Hosted PBX needs no upfront capital investment, even desk phones and set up are included with service. With Tierzero, the cost is priced per user at $25 per month/per person. That single-per-user price gives your business a full feature managed service with instant access to a team of experts who ALWAYS answer your calls in seconds. Tierzero guarantees instant customer care 24/7 - a promise that has set it apart from competitors since 1997. 

  • Do I Have to Use Tierzero Phones?

    No. The cost per user drops to $19.95 if you use your own desk phone.

  • Is It Easy To Make Changes With Hosted PBX?

    Yes. Hosted PBX is easily scalable. It lets you add users and/or locations effortlessly.  As your business grows, your system grows with it. Conversely,  you can scale back to remove users just as easily. In times of uncertainty that can bring great peace of mind. 

  • What Features Are Included With Hosted PBX?

    Tierzero’s Hosted PBX solution comes with over 40 standard features. All the greats like caller ID, call hold, call waiting, call forwarding, voicemail, find me/follow me, call conferencing.

  • Does Hosted PBX Work On A Mobile Device?

    Yes, Hosted PBX also works on a mobile app. Now you have access to all the same features on your desk phone, through your cell phone, no matter where you are in the world.

  • Will Hosted PBX Work With My Internet?

    Hosted PBX is delivered over any form of Internet. We’d prefer you used ours, but essentially any broadband, cable, LTE, fiber, fixed wireless, ethernet-over-copper, or whichever source you have in place. Tierzero can harness one or more of those Internet sources into your own private hosted phone network to be managed by our specialized care team. Each desk phone will connect either wirelessly or by plug to a switch. It doesn’t matter where your business is located geographically, or if there are multiple office locations as well as multiple remote workers all using different Internet services. As long as each employee uses the configured phone we supply - they can start communicating inside your company network immediately. 

  • What If My Business Has Multiple Locations?

    Tierzero has considerable experience deploying Hosted PBX phone systems for businesses with multiple locations and remote employees. Again, it doesn’t matter what kind of Internet service the remote locations or workers use. As long as they connect the device we deliver or access the mobile app, they are inside your company network enjoying all the same service and features available at HQ.
