Business Phone Systems in Tempe, Arizona
Velocity Phone Systems is the business-phone practice of Velocity Technologies, a Tempe managed IT firm founded in 2004. We are headquartered right here at 4500 S Lakeshore Dr, so the team that designs and installs your phones is local, not a call center three time zones away.
From ASU-adjacent startups to established East Valley operations, we design, port, install, and support the right system for how you actually work — hosted VoIP, on-premise PBX, a hybrid of the two, SIP trunking, or Microsoft Teams Phone.

Phone systems for how Tempe works
Tempe runs on a mix of ASU-area startups, professional offices, light industrial shops, and retail along Mill Avenue and Rural Road. No single phone model fits all of them, so we start with how your team handles calls and recommend from there.
On-premise PBX
A system that lives in your building for businesses that want local control, existing analog gear, or specific call-flow and compliance needs.
Hybrid, SIP, and Teams Phone
Keep an on-prem PBX while adding cloud flexibility, replace aging trunks with SIP, or turn Microsoft Teams into your phone system — whatever matches your stack.
On-site install and support in the East Valley
Because our office is in Tempe, supporting nearby businesses on-site is routine. We can stand in your wiring closet, not just remote in from somewhere else.
Local site survey
We walk your space, check network readiness, and map your call flows before quoting anything — in person when it helps.
Hands-on installation
We mount and configure equipment, verify your network can carry voice cleanly, and test phones at every desk before go-live.
In-person training and follow-up
Staff learn the new system face to face, and the same team handles questions and changes after you are live.
Local number porting without the drama
Keeping your existing Tempe and Phoenix-area numbers is usually the biggest worry in a phone change. We plan the port so your lines do not go dark.
Keep your numbers
We port existing direct lines, main numbers, and toll-free numbers from your current carrier so customers reach you the same way.
Coordinated cutover
We schedule the switch around your business hours and confirm every number rings correctly before retiring the old service.
No guesswork on timing
We handle the carrier paperwork and set realistic dates so you are not left wondering when the change actually happens.
One accountable team, the right recommendation
We sell outcomes, not a single product line. Because we install and support every model, we have no reason to push you toward one over another.
Vendor-neutral advice
We recommend hosted, on-premise, hybrid, SIP, or Teams Phone based on your needs and budget — never a one-size answer.
Design that fits your workflow
Auto-attendants, ring groups, voicemail, and call routing are built around how your team actually answers calls.
Support from the people who built it
As part of Velocity Technologies, your phones are backed by a full managed IT team that already knows your network and your setup.

Questions buyers ask before choosing a phone system.
Where is Velocity Phone Systems located?
We are headquartered at 4500 S Lakeshore Dr, Suite 300, Tempe, AZ 85282 — the home office of Velocity Technologies, a managed IT firm founded in 2004. Being based in Tempe means we can support local businesses on-site.
Do you only serve Tempe?
No. Tempe is our home base, so we are especially hands-on across the East Valley — Phoenix, Chandler, Mesa, Scottsdale, and Gilbert — and we support businesses nationwide as well.
Can you come to my Tempe office in person?
Yes. On-site visits are routine for nearby businesses. We can run a site survey, install equipment, check your network, and train your staff in person rather than only working remotely.
Which phone system is right for my business?
It depends on how your team works. We design and support hosted VoIP, on-premise PBX, hybrid setups, SIP trunking, and Microsoft Teams Phone, and we recommend the model that fits your needs instead of forcing one.
Can I keep my current phone numbers?
Yes. We port your existing local and toll-free numbers from your current carrier and coordinate the cutover so your lines stay live during the switch.
What makes Velocity different from a national VoIP provider?
One accountable team designs, ports, installs, and supports your system — and we are local. Because we are part of a Tempe managed IT firm, the people who set up your phones also know your network and answer when you call.
