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.

The terms FXS and FXO come up in almost every conversation about analog telephony and VoIP integration, but they’re rarely explained clearly. They’re not interchangeable, and confusing them during a phone system setup creates problems that can be difficult to troubleshoot after the fact.

Your business phone numbers are yours to keep, regardless of which carrier currently manages them. The Federal Communication Commission’s (FCC) local number portability rules guarantee that right, but the transfer process has requirements that you need to understand before you begin.

Protecting the business in a dispute is one reason to record calls, but it's far from the only one. When call recording is part of a broader communication and performance strategy, those conversations can become a valuable source of information for improving employees, operations, and customer interactions.

Dropped calls and unreachable phone lines can quickly take a toll on customer service and productivity. Here are seven ways to improve Voice over Internet Protocol (VoIP) reliability and build a backup plan that keeps business conversations flowing.
Look beyond price when choosing a VoIP provider
A low-cost VoIP plan may not be a bargain if the provider suffers frequent outages or offers poor customer support.

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.

The same Voice over Internet Protocol (VoIP) infrastructure your business relies on for day-to-day communication is quietly generating a wealth of data about how your teams operate and how your customers feel. VoIP analytics is the layer that makes that data readable, searchable, and useful for everyone from IT managers to contact center supervisors.

Every phone interaction shapes how people see your company, including the minutes they spend waiting. Refreshing your Voice over Internet Protocol (VoIP) on-hold messages can help callers stay informed, feel valued, and remain connected until someone is ready to assist them.
