SonicVoIP is a business VoIP provider for the Inland Empire, serving companies throughout San Bernardino County and Riverside County with hosted PBX, on-site installation, number porting, business texting, mobile apps, and internet redundancy. Based in Victorville, we install and support phone systems in person rather than shipping a self-setup box — and as the VoIP division of Sonic Systems, we make sure your network is ready for reliable voice first.
One Region, Two Counties
The Inland Empire spans San Bernardino and Riverside counties and is home to millions of residents and tens of thousands of businesses. It stretches from Ontario, Rancho Cucamonga, and Corona on the western valley floor, across San Bernardino and Riverside, out to Temecula in the south and up through the Cajon Pass into the High Desert cities of Victorville, Hesperia, and Apple Valley. "Inland Empire" is the name local businesses and customers actually use — even though the counties carry different official names.
That scale is why a one-size-fits-all, ship-it-yourself phone service rarely works here. A distribution center in Fontana, a dental office in Murrieta, and a law firm in Riverside all need different call flows. We design each system around how your team works, install it at your location, and stay local for support.

Law firms, finance, real estate, and consulting offices get auto attendants, business texting, and mobile apps so every client call is answered and logged — wherever staff are working.
