On Premise Phone System Solutions

MiVoice Business

The Mitel MiVoice Business is a highly scalable, proven business communication platform that delivers voice, unified messaging, mobility, presence, conferencing, collaboration, applications, and more.

A Platform for Success

The Mitel MiVoice Business phone system is designed to meet the needs of businesses from 5 to 65,000 users, whether they have a single site or multi-site networks that span the globe.

Built-in Core Applications

Mitel’s MiVoice Business has many embedded features that complement unified communications solutions:

Mobility – Dynamic Extension

The Mitel MiVoice Business has an embedded Dynamic Extension solution that allows users to select up to eight different devices or numbers to act as their answer point. By grouping multiple devices under the same user number, all their phone numbers are effectively collapsed into one, so callers can reach users regardless of which number they call.

Mobility – Hot Desking

Hot Desking enables employees to log onto any designated phone, located at any of your offices, or even outside of the business offices. All calls are routed to the device they are logged into so callers can always reach them by dialing their office extension.

Deployment Flexibility

Distributed, centralized, and public cloud – you can choose your deployment strategy. In addition, virtual deployment allows you to take advantage of the business continuity services available through VMware.

Unified Messaging

Employees have anywhere, anytime access to messages with an integrated, fully-featured voice mail system, Unified Messaging, and an automated attendant.

Web-Based Management

An administrator can administer a multi-platform MiVoice Business solution from their web browser as if it was a single platform solution. System changes are automatically synchronized across the solution, and management control and tasks can be delegated across the organization, rather than relying on a centralized point.

Standards-Based Architecture

The Mitel MiVoice Business operates across any LAN / WAN infrastructure, coupled with embedded native support for standards-based networking such as SIP, Q.SIG, and DPNSS, offering businesses the ability to protect existing investments irrespective of legacy PBX, while delivering all the advantages of a converged infrastructure.

MiVoice Office 250

Increase productivity and save money with a phone system built for your business.

Small and medium-sized businesses deserve a phone system that’s built around their unique needs; that is why TSI (Tele-Solutions, Inc.) is proud to offer the Mitel MiVoice Office 250. This revolutionary business application platform is more than “just a phone system” as it connects employees from any location- increasing productivity and lowering your communication costs.

Enhance Productivity

The Mitel MiVoice Office 250 ensures small and medium-sized businesses are more flexible and responsive. Through a complete suite of out-of-the-box business productivity applications, your business will benefit from reduced costs and enhanced staff productivity. The Mitel MiVoice Office 250 delivers standard applications including:

Unified Voice Messaging with Automated Attendant

No need for a receptionist or operator to disperse your calls. With the Mitel MiVoice Office 250, you have the ability to set up your own custom automated “auto” attendant that transfers callers to your custom list of extensions based on user or department.


The Mitel MiVoice Office 250 allows for embedded teleworking. This feature allows remote users access to all the same features and functionality of their office colleagues. Home-based and remote workers can be easily reached by co-workers and customers alike.

Hot Desking

Hot Desking enables employees to log onto any designated phone. All calls are routed to the device they are logged into so callers can always reach them by dialing their office extension.

Automatic Call Distribution

Receive a large volume of inbound calls? Let Mitel MiVoice Office 250 disperse your incoming calls to contact center agents or specific employees through automatic call distribution.


Allow your phone system to work for your employees even when they can’t be in the office. Twinning, on the Mitel MiVoice Office 250, allows for your employees to sync an alternative number (usually their cell phone) to their desk extension. With this feature enabled, whenever their extension rings, their second device can also pick up the call.

Unified Communications

The Mitel MiVoice Office 250 supports a range of advanced Unified Communications applications that give users the ability to integrate their desktop and mobile devices with the telephone system. Features like click-to-dial and co-worker presence information help users communicate more efficiently.

Mobile Hand-Off

The Mitel MiVoice Office 250 allows users to seamlessly move calls to and from their desk phone and mobile device, giving them the ability to easily move in and out of the office without any disruption.


TSI (Tele-Solutions, Inc.) offers a number of call reporting solutions that give business owners a clear view of their voice usage and its associated costs in both historical and real-time environments.

Meet-Me Conferencing

Optimize your efficiency by allowing for easy-to-use conference calling as an alternative to face-to-face meetings. With the Mitel MiVoice Office 250, you can establish conference numbers to share across multiple users within a group.

The Mitel MiVoice Office 250 uses a software and hardware platform that combines the best of data networking and TDM switching architectures. It supports MiVoice Digital and IP telephones, IP networking for up to 99 sites and is designed to be customized with add-on modules & processors (all in a form factor that is optimized for shelf-top, rack-mount, and wall-mount scenarios).

How it all works

With Cloud Phone Systems, you get a business phone system that just works, but for those of you interested in what’s under the hood, let’s break it down. The brains of the system reside in geo-redundant data centers and continue to provide service even in the rare event one goes down. Information and voice calls securely traverse the public Internet to reach their final destination using voice over Internet protocols (VoIP). Employees enjoy the same communications functionality regardless of whether they are in an office, on the road, or working from home.
