Onsite PBX · SIP · VoIP
Keep your PBX. Cut what it costs.
Get the flexibility of a cloud phone system without replacing the PBX you own. SIP trunking replaces your old phone lines with cloud connections, so voice and data run over one network.
Onsite PBX
The system you own still has years in it.
A modern phone system has to do more than make calls: voicemail, auto attendant and call groups should be standard. Keep the PBX you already own and get those features — with a return on the hardware you’ve already paid for.
We provide low-cost, high-quality VoIP for business, along with complete PBX planning, installation, setup, service and support. If you have a legacy PBX, we can convert it to run on VoIP for a fraction of the cost of replacing the whole system.

Onsite or cloud?
The difference, side by side.
An on-premise PBX (private branch exchange) is a phone system that physically sits in your building. You own and manage its hardware, software and lines, and it routes calls in and out of your organization.
| Onsite PBX | Onsite PBX + SIP trunks | Cloud PBX | |
|---|---|---|---|
| Where it lives | Hardware in your building | Hardware in your building | A provider’s data centers |
| Who maintains it | Your IT team | Your IT team; we manage the lines | The provider |
| Phone lines | A separate line for each simultaneous call | Cloud trunks over your internet connection | Virtual lines, included |
| Adding phones | Buy more IP phones (plus licenses, if needed) | Same | Added to the service plan |
| If the building goes offline | Calls stop | Calls fail over to another number or cell phone | Calls ring on mobile apps |
| Best when | You own a system you like | You own a system and want lower costs | You want no hardware at all |
A cloud PBX is hosted off-site by a provider, usually in data centers, and managed over the internet. You don’t own or maintain any PBX hardware or phone lines; the provider handles upgrades, backups and security.
