Simplify with One Bill

Keep your current internet provider, and get one bill for your internet + phone. No other major VOIP provider offers this.

If phones go down, ISP's blame VoIP and VoIP providers blame the ISP. Sun helps you avoid that headache with just one company to call.

    Who is Sun Communications?


    We are a Nationwide Digital Communication Provider for commercial and government entities.  With a coast to coast network of hardware engineers we can easily configure and properly wire your business location and accommodate expansion. Our clientele are primarily professional service companies and organizations such as doctors, dentists, attorneys, medical clinics, business service providers, government entities and non-profit organizations.  If necessary we can work within an existing PBX / SIP infrastructure.

    We work only with commercial, non-profit and government entities.  Referrals can be provided upon request.


    We are a full-service digital communications provider. If you need a new internet service provider, or need to integrate telecom with your software systems, add HIPAA Compliant Web Chat, Video Conferencing or Call Center solutions or outsource to a call center that provides SMS-chat-telephone answering services. Perhaps you want fail-over to cell phones; so if the power goes out, you never miss a customer or patient's call? We compete directly with AT&T and Verizon, but separate ourselves through a broader set of services, cost savings and an assigned digital communications expert.


    We assign you a knowledgeable Account Manager who will be your single point of contact to take care of any needs that arise. Our Account Managers are experts who can help you with any digital communication product or service.  No call center IVR and no getting passed around.  Ahhhh.

    99.9999% UPTIME

    We provide tier one reliability.  With our fail-over you improve to 100%.
