VoIP and collaboration offerings

C Spire sells enterprise VoIP phone systems as part of a broader unified communications (UCaaS) practice.

Its hardware lineup is built around Cisco and Webex equipment: multi-line Cisco desk phones from the 8800, 7800 and 6800 families, Cisco DECT cordless handsets (including a rugged model for tougher work settings), Cisco conference phones, and Webex video devices such as the Board Pro, Desk Pro, Desk Mini and Room Bar.

Its FAQ notes that the voice service uses quality-of-service prioritization and redundant systems, that the C Spire team manages porting of existing numbers, and that continuity options include battery backup, sending calls to cell phones, and cloud failover. The UCaaS platform can tie into Salesforce, Slack, Microsoft Teams and Google Workspace, and it supports single sign-on and custom automated workflows.

Beyond phones, the business portfolio covers:

• Business fiber internet and managed networking, including SD-WAN and managed Wi-Fi
• Managed IT services with round-the-clock monitoring
• Managed security, firewalls and cybersecurity guidance
• Cloud solutions and regional data center colocation
• Business wireless plans and devices
• Professional services and IT consulting

How it works with clients

New customers usually begin by requesting a consultation, after which a certified engineer contacts them to learn about their current environment and goals before designing a tailored solution. The company says its business team includes more than 200 engineers, and clients are assigned dedicated account teams.

VoIP customers get technical help at any hour, proactive oversight of their systems, regular updates, staff training and continuing optimization. An online portal, My C Spire Business, lets customers handle billing, track performance and open support tickets themselves.
