Cloud VoIP and Hosted PBX for Raleigh Businesses
Not ready to commit to on-premise hardware? A cloud, or hosted, phone system runs your entire phone system off-site and gives Raleigh businesses the flexibility to add a line the day you hire, or open a new location without waiting on equipment.
- Free auto attendant to route patients, clients, and customers to the right department
- Voicemail-to-email with transcription
- ConnectUC mobile app so calls follow you between downtown, RTP, and home without giving out your cell number
- Support for multiple locations – Raleigh, Durham, and Cary 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 Raleigh for the full feature set.
How the Switch Works
We start with a walkthrough of your current phone bill and call flow. Raleigh is one of the fastest-growing metro areas in the country, and a lot of the businesses we talk to are either outgrowing an old analog system or trying to connect a second office in Durham or Cary to their main line. Many are still paying AT&T, Windstream, Charter, or Spectrum for traditional phone lines at roughly double what a SIP trunking or hosted solution costs. We can usually cut that bill by 30 to 50 percent while adding features your old system never had, and we schedule the cutover so it doesn’t interrupt business.
Built for How Raleigh Does Business
Raleigh anchors the Research Triangle alongside Durham and Chapel Hill, and the businesses here reflect that mix: state government offices downtown, a fast-growing tech and biotech base around Research Triangle Park, medical and professional practices in North Hills, and small businesses opening across every corner of the metro. A downtown law firm needs a different call flow than a biotech startup near RTP or a multi-location medical practice with patients calling in from across the Triangle.
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 across multiple Triangle locations.
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 Raleigh offices.
Why Raleigh Businesses Choose DS1 Phone Systems
We’ve been installing and supporting business phone systems since 1994. No contracts, free tech support, and free changes to your system whenever your business needs them – with the kind of same-day, local service the big national providers can’t match.
