Our office phone bill keeps climbing. Should we switch to VoIP phones?

Traditional business phone lines are a legacy product with legacy pricing: per-line charges, feature fees, and hardware contracts that quietly climb. VoIP (voice over IP) replaces the phone company's copper with your existing internet connection, and for most small offices the move cuts the monthly bill meaningfully while adding the features modern businesses actually want: ring groups and auto-attendants, voicemail delivered to email, desk phones and mobile apps sharing one number so calls follow people out of the office, and easy adds and changes without a technician visit.

The honest caveat is that VoIP is only as good as the network under it. Calls are real-time traffic sharing the wire with everything else, so a congested network or an ISP-grade router produces choppy audio and blame aimed at the phones. Done properly, the network prioritizes voice traffic (QoS), the internet connection is sized for simultaneous calls, and quality is indistinguishable from or better than the old lines. This is why phone quality questions are really network questions, and why having one provider responsible for both (see our question on one company handling everything) avoids the finger-pointing.

Timing-wise, the decision often makes itself: when the old system needs a repair, when the contract renews, or when you move offices. Number porting is routine (you keep your numbers), and cutover can run in parallel so the office never misses a call.
