Cloud VoIP Setup & Number Porting
Your existing business number ported to a cloud VoIP provider with the cutover timed so there's no gap in service and no missed calls.
VoIP & Business Phone Systems
A phone line tied to a physical building at the office is a phone line that dies with the internet or the power. Ghosxt sets up cloud VoIP for California small businesses that ports your existing number, rings through to mobile, and keeps working when the office can't — configured by a DoD-cleared engineer, not left on the default settings.
Built by a DoD-cleared engineer — a phone system, not a science project.
The problem with a phone line tied to a building
An old on-premise phone system is a single point of failure: it goes down with the internet, the power, or the box in the closet nobody has serviced in years, and the business goes silent right when a customer is trying to reach you. Cloud VoIP moves the phone system off that box entirely — calls route through the internet to whatever device your team actually has in hand, and a local outage doesn't have to mean a missed call.
We've set this up across client environments where the main line couldn't afford to go dark — reservation desks, dispatch lines, front-office phones — and it's consistently one of the highest-value, lowest-drama moves a small business makes.
What we set up
Mobile & Softphone Integration
Calls ring through to mobile phones and desktop softphone apps, so the office line isn't tied to a desk anyone has to be sitting at.
Auto-Attendant & Call Routing
Professional call menus and routing rules that get callers to the right person or department without a receptionist manually transferring every call.
Microsoft Teams Phone Integration
Calling built directly into Microsoft Teams, so your team makes and takes calls in the same app they already use for chat and meetings.
E911 Compliance
Emergency calling configured so dispatchers get the correct physical address for every extension, not just a generic company location.
Outage Failover
Automatic routing to mobile or a backup number when your primary internet or power goes down, so an outage doesn't take your phones with it.

VoIP setup is typically part of a broader Microsoft 365 and cloud deployment, and once it's running it's supported the same way as the rest of your environment through managed IT — monitored, patched, and covered by the same help desk as everything else, not a separate vendor to manage on the side.
VoIP & Business Phone FAQs
Do we need new hardware for VoIP?
Usually not much. Most modern VoIP runs on softphone apps on the computers and phones your team already has, with physical desk phones optional for the roles that want one. We'll size the right mix for your team rather than defaulting to a phone on every desk.
What happens to our phones if the internet or power goes out?
We configure automatic failover so calls route to mobile phones or a backup number when your primary connection drops, so an outage doesn't mean your business goes silent. This is one of the most common reasons small businesses move off an old on-premise phone system.
Can we keep our existing phone number?
Yes. Number porting to a new VoIP provider is standard, and we handle the process and timing so there's no gap in service and no missed calls during the cutover.
Does VoIP work with Microsoft Teams?
Yes. Microsoft Teams Phone lets your team make and receive calls directly inside Teams, on the same app they already use for chat and meetings, instead of running a separate phone system alongside it. We set this up as part of a broader Microsoft 365 deployment when it's the right fit.
