What is Hosted VoIP?

Hosted VoIP (Voice over Internet Protocol) is a telecom service that allows phones located at customer location(s), to connect via the internet, to a Cloud-based phone system. These cloud systems and associated phone lines are purchased, maintained and paid for by Hosted VoIP service providers, not customers. The reduced expense and enhanced functionality of Hosted VoIP is quickly eliminating the need for traditional phone systems and phone lines, while allowing employees to work remotely as if under one roof.

Successful Hosted VoIP deployments require expertise in selecting the right product and potentially making modifications to customer networks and internet connections. TC Tech Systems, with its Telecom and IT expertise, are uniquely qualified to help every step of the way. If you’re considering the shift from office phone systems to remote or work-from-home systems, contact us today or visit our Managed IT Services page for more on how we can help.
