Pricing in this industry is intentionally confusing, with per line fees, per user fees, add on charges, and bundled packages that make comparisons difficult.
Answer: There's no single right number, since cost depends on user count, call volume, and features needed. But the useful question isn't "what's the cheapest option," it's "what's included at that price." A cheap quote that excludes support, has hidden overage fees, or locks you into a long contract often costs more than a slightly higher quote with everything included. Ask for an all in monthly cost with nothing left off the page.
