Business Phone Systems

A business phone system should ring the right person every time, follow your team to their laptop and cell, and cost less than the old one. Onsite 24/7 Services designs, ports and supports Microsoft Teams Phone and hosted VoIP systems for south Denver metro businesses.

Teams Phone and VoIP

• Microsoft Teams Phone: make and take calls from Teams on your desk phone, laptop or cell, using the Microsoft 365 you already pay for.
• Hosted VoIP: cloud phone systems with desk phones for offices, shops and warehouses that need traditional handsets.
• Number porting: keep your existing main line and direct numbers. We manage the port so there is no gap in service.
• Call routing: auto attendants, ring groups, hunt groups, after-hours rules and voicemail to email.
• Multi-location: one system across every office, with extension dialing between sites.

Why replace an old system

Older on-premises phone systems are expensive to maintain, hard to change and tie calls to a desk. A modern system lets staff work from anywhere, gives you call reports, and is usually cheaper per user once the old maintenance contract and phone lines are retired.

How we handle the switch

We inventory your current numbers, lines and contracts, design the call flow with you, schedule the port for a quiet window and test every number before cutover. Your staff get a short walkthrough, and we stay on call for the first week.
