We get asked all the time, do I have to upgrade from my old Nortel, Panasonic, Grandstream or other PBX. Well it is true that the old systems can’t do what a Hosted VOIP solution can do. Below are a few reasons why sticking with your current solution might be right for you.

In today’s cloud-first world, it’s easy to feel pressure to ditch your legacy phone system and jump head-first into a hosted VoIP solution. And while hosted systems have their advantages—like remote access and scalability—they may not be the best fit for every business. At TIS Ltd., we specialize in both traditional and modern phone systems, and we’ve seen firsthand that there are still plenty of good reasons to hang onto your old Nortel PBX.

1. It Still Works (and Works Well)

Nortel systems were built to last. If your existing PBX is stable, reliable, and still meeting your business needs, there may be no urgent reason to replace it. “If it ain’t broke, don’t fix it” holds a lot of weight—especially when dealing with something as mission-critical as your phone system.

2. Full Control, No Dependency

With an on-premise PBX, you’re not reliant on an internet connection or a third-party provider to make and receive calls. That control can be especially valuable in areas where internet connectivity isn’t always stable. For example at TIS we service some golf courses where reliable internet hasn’t been readily available.

3. Serviceable with the Right Expertise

At TIS Ltd., we help businesses modernize their legacy Nortel systems without ripping them out. Some small business owners prefer the simplicity of an on premise solution and at TIS we have the expertise to keep you running smoothly.

In Summary:
Hosted phone systems are a great fit for many organizations, but they’re not always the best or most cost-effective solution for everyone. If your Nortel PBX is still working for you, there’s no harm in keeping it—and even enhancing it with the right support.
