Let’s take a look at our core products and services.

Phone System Sales, Installation And Service 

PBX Phone Systems 

PBX phone systems are advanced business phones that allow you to control all aspects of your company’s communication. You can set up different extensions for your employees, call routing, and more.

One of the most popular features is the ability to route calls based on room number or extension number, allowing you to direct calls from one location or employee directly into another office at another site without transferring them manually.

VoIP/SIP Phone System 

These are more advanced business phone systems that allow you to make calls over the internet instead of through traditional landline connections as with conventional analog systems.

With this type of system, it’s possible to have unlimited calling anywhere in the world without incurring expensive charges – even if there is no physical connection between two parties.

This means no more costly long-distance fees. The cost savings can add up quickly, so many businesses prefer this option to others when choosing their new phone system solution.

This is because it gives you complete freedom over how much they spend each month on communications services. You can still afford other necessities such as rent payments, or payroll checks every two weeks like clockwork (or whatever day/ schedule works best).

If your business uses a Vodavi or Inter-Tel phone system, we can help you get things up and running again. We’ll install the necessary equipment and configure it to your specifications.

If there are any problems with your current configuration or network setup, rest assured, this is our specialty.

Comprehensive Onsite End-user Training 

If you have your own in-house IT department or prefer to work with another outside IT vendor, we will coordinate with them at no additional charge to make sure they have the information and technical support they need to ensure seamless integration of our phone system with your computer network.

We understand the sheer importance of having staff who are well-trained and fully knowledgeable. And so, we offer free staff training to your team.

The training is conducted by trainers/technicians who are personable and have a comprehensive understanding of the systems. This will help in providing a thorough onboarding experience.

In the event that an issue arises or your staff members require a bit more support, we are more than happy to provide free training and support over the phone.

In some cases, companies have their own IT departments (in-house or externally). We cater to all scenarios; thus are more than happy to coordinate with them at no additional charge.

Phone System Adds/Moves/Changes 

Looking to add new lines to your existing phone system? We’ve got you covered.

Or, if you have a new phone system and need to move your existing lines over, we can assist with that migration too.

If you’re looking to change the configuration of your phone system, we will happily help with that as well.

And finally, if something is not working correctly or not working at all, we’ll be happy to troubleshoot and fix any problems for you (more on this below).

24/7 Technical Support & Response 

We’ve been in business long enough to appreciate two things – it is very stressful when a problem arises and you need to get operations back up and running (especially when you’re reliant on a third-party provider), and running a business in this economy is expensive and sometimes breaking even is a tough ask.

How do we accommodate this?

In the event that an issue pops up, we will work tirelessly to sort it out so that your business is minimally affected. We can assist over the phone in order to save you the cost of a service call-out. We can also use screen-sharing to illustrate the issue in real-time, and remote access to diagnose and fix the problem.

If the issue requires a more hands-on approach, we can troubleshoot and program your system offsite at our regular remote service rate. If the problem is hardware-related or too complex to be fixed remotely, we will dispatch a technician to your location at our regular service call hourly rate plus trip charge.

Our customer service team is always happy to answer any questions and assist with any concerns or issues. You can contact them by phone or email. Call us at (602) 993-3545 anytime to reach our on-call support team.

In terms of costs, we pride ourselves on not charging higher fees for emergency, after-hours service.
