Integrated, Analog or Cellular

R-Square Correlations broad carrier relationships provide access to the most competitive pricing for voice services of every nature.

If you are looking for more reliable and competitively priced voice-only services for your business we provide our clients Local, Long Distance, International, Toll-Free, Conferencing and Cellular voice service options over the following circuits or delivery mechanisms:

  • Hosted VoIP
  • SIP (Session Initiated Protocol)
  • UCaas (Unified Communications-as-a-Service)
  • PRI
  • CCaas (Contact Center-as-a-Service)
  • Lync/Skype for Business


Reliable internet services are a necessity for any business, and the exploding demand for greater bandwidth has resulted in the development of a growing array of alternative internet connectivity options.

R-Square Correlations knows that for some businesses a simple inexpensive broadband connection will suffice. Increasingly, though, as more businesses move to cloud based services, businesses are finding that a single dedicated internet service does not provide the necessary resilience or 100% uptime that they require. For these businesses we recommend secondary and sometimes even tertiary internet connectivity over a number of different provider networks. Our broad spectrum of service provider relationships allows us to easily fulfill those needs while also providing our clients the best possible pricing for those services.

Other businesses require not only high bandwidth but also low latency connectivity to provide differentiated capabilities over their peers and competitors. Again, R-Square Correlations can help identify the lowest latency connectivity options for your business.
