IP PBX may have drawbacks for some companies that are not equipped to use it. Here are some limitations to consider:
Requires advanced technical skills: Managing an on-premises PBX is not for beginners. It requires experience installing and configuring Linux operating systems. But if you are a Linux fan system admin and have experience with open source software like FreePBX, you have nothing to fear.
Doesn’t support remote work: This factor is a huge drawback in 2021. Even when having IP connectivity, on-site PBX phone systems struggle with supporting remote work.Common workarounds include downloading an app to your cell phone and signing in from there.
Can only scale so much: IP PBX solutions scale up according to the number of users you have. If your team expands over the PBX’s capability, though, you can face the system stalling or returning busy signals.
Limited features: IP PBX phone systems typically offer key features such as video conferencing, mobile device support, and instant message as extra features for an added price. This can be an issue for small businesses that cannot go over budget.
