Adding phones to a branch office seems simple, until calls start dropping during busy periods or audio quality degrades for no obvious reason. Most VoIP problems trace back to decisions made before a single handset is installed: how many concurrent calls the connection can support, whether latency and jitter are low enough to preserve voice quality, and whether the WAN has genuine headroom once other traffic is factored in.

For businesses choosing a phone system, the question is no longer simply how to make and receive calls. It’s where those calls should live: on an internet-based VoIP system or a cellular network using VoLTE. Each has its advantages, and the right fit depends on your team’s needs.

Teams Phone has supported multiple assigned phone numbers for some time, but mobile users have had limited access to that functionality. A Microsoft 365 update that rolled out from late July through mid-August 2026 extends full multiline capability to Teams mobile on iOS and Android, bringing mobile users in line with the desktop experience.

Switching to a new phone provider doesn’t have to mean starting over with new numbers. Number portability — the right to take your existing phone numbers with you when you change carriers — is a federal protection established by the Federal Communications Commission (FCC) and available to virtually all businesses.

A single phone call can contain more information than anyone can reliably remember. Handwritten notes may not capture every detail and can be time-consuming. Call recording is a standard feature in modern VoIP systems that gives businesses an accurate, searchable record of every conversation.

VoIP downtime can bring sales calls, customer support, and team collaboration to a grinding halt. These seven practical steps will help your business build a more resilient phone system, minimize disruptions, and keep your team connected when technical issues strike.

Unexpected spikes in network traffic or international charges usually indicate that bad actors are exploiting your communication tools. Knowing what to watch out for and how to respond enables your IT team to isolate threats and restore reliable voice services quickly.

AI is creeping into more parts of business than most people realize.

It writes emails, helps analyze data, and powers tools your team might be using every day.

And in many cases, it’s been adopted quickly.

Which is great… until you stop and think about what would happen if something went wrong.

There’s a new type of scam doing the rounds… and this one’s a little more convincing than most.
