Sunco started as an installation and repair company providing customers in Edmonton and across Alberta with fast, reliable service at affordable prices. Almost 20 years later, we’re still the first choice in telephone servicing for businesses across Western Canada. We’re proud that many of our customers have been with us since we opened our doors.

Trust the Sunco team to keep your systems running smoothly

Our focus on long-term relationships and local, in-person tech support sets us apart. Sunco customers never have to wait on hold with large, impersonal call centres. If we can’t troubleshoot and fix your issue remotely, our friendly and experienced technicians will come to your place of business with everything they need to diagnose and repair your system. If we can’t fix it right away, we’ll offer a temporary solution to get you back up and running while we replace or upgrade the necessary parts.

Moving locations or expanding/downsizing your office?  We specialize in complete system moves, additions or changes (MACs).  Our technicians can complete all the necessary modifications to your system or we can train you to handle basic changes like adding new phones and resetting passwords.

There are several important things to consider when moving your telecom system to a new location.  Leaving yourself ample time (at least six to 12 weeks) to have your telephone numbers “ported” or moved to your new premises is critical.  Sunco can help with every step of the process.  We have summed up this important information in our blog Telecommunications Moving Checklist.
This will depend on your exact business needs. At Sunco, we take the time to get to know your company and the challenges you face so we can make the best possible recommendation for your circumstances. If the cost to repair your system is too high, or if it’s likely that a repair will only be a temporary fix, we may recommend that you upgrade to a new system. You may also be interested in the increased functionality that an upgrade would provide to your business. We always recommend replacing your system if the ‘main system’ (also called the core unit or the Key System Unit -- KSU) has failed. This is the ‘brains’ of a system, and once it fails, repairs become very difficult and expensive. Depending on the age of your system, your replacement KSU may be a refurbished unit, so there is no way to guarantee how long it will last.
Depending on the severity of your problem, we may be able to troubleshoot it right away on the phone. If not, we can come to your place of business within one to three days. Once we are on site, repairs can take as little as one day, depending on parts and the type of repair that is necessary. If you require emergency repairs, we will do our best to help on the same day if possible.
We know how frustrating and disruptive it can be if your phone system goes down and business grinds to a halt. We offer 24/7 emergency support to get you back up and running as fast as possible. Emergency Phone System Support
We suggest you check or replace your cords, which typically eliminates static.
  • Make sure the cord is securely plugged into the wall.
  • Take a working phone from another office and plug it into the same outlet to check whether or not you get dial tone.
  • Check for lights on the phoneset to see if it is connected to power.
Put the phone on speaker and see it it works.  If it does,  it could be a problem with your handset or cord.
Unfortunately you won’t be able to solve this one on your own. Give us a call and we can help to reset the password. It’s a quick fix!
