Cloud VoIP and Hosted PBX for Cary Businesses
Not ready to commit to on-premise hardware? A cloud, or hosted, phone system runs your entire phone system off-site and gives Cary businesses the flexibility to add or remove lines as your team grows.
- Free auto attendant to route clients, patients, and customers to the right department
- Voicemail-to-email with transcription
- ConnectUC mobile app so calls follow you off-site without giving out your cell number
- Support for multiple locations – office, warehouse, and home all on one system
- Yealink desk phones that work seamlessly with the hosted platform

Prefer a fully hosted solution instead of on-site hardware? Take a look at our cloud phone systems for Cary for the full feature set.
How the Switch Works
We start with a walkthrough of your current phone bill and call flow. A lot of the Cary businesses we talk to are software and professional-services firms clustered near the SAS Institute campus and along Weston Parkway, and many are still paying AT&T, Spectrum, Windstream, or CenturyLink for traditional phone lines at roughly double what a SIP trunking or hosted solution costs. We can usually cut that bill in half while adding features your old system never had, and we schedule the cutover so it doesn’t interrupt business.
Built for How Cary Does Business
Cary grew from a small railroad town into one of the fastest-growing suburbs in the Triangle, and today it’s home to SAS Institute’s sprawling corporate campus along with a corridor of tech and professional-services companies near Weston Parkway and MacGregor Downs. Downtown Cary’s revitalized district mixes retail, restaurants, and startups with the town’s family-friendly, parks-first character, from the Koka Booth Amphitheatre to the USA Baseball National Training Complex. A boutique in Downtown Cary needs a different call flow than a multi-location software company or a professional services firm.
Because we’ve installed phone systems for businesses across North Carolina for over 20 years, we size every system to the business it’s built for, whether that means a compact system for a small office or a fully expandable IP system for a company with several hundred extensions.
Structured Cabling and On-Site Support
Moving into a new office or just tired of a rat’s nest of cabling in the server closet? We provide structured cabling for both voice and data, so your phone system and your network are both built on infrastructure that will last.

Still Running an On-Premise System?
If you already have an NEC, Avaya, ESI, or Nortel system in place, we can service, expand, or replace it. DS1 Phone Systems is an authorized dealer for ESI and NEC SL1100 phone systems, and we’re familiar with legacy Avaya IP Office and Nortel Norstar equipment still running in older Cary offices.
