Jacksonville-based Ennovative Commerce Solutions announced on Friday that it installed a new, company-wide VoIP system from TelCove, a provider of business telecom services to enterprise customers and carriers.   With the TelCove Network VoIP Service (TNVS) in place, customers are able to administer the VoIP phones in their enterprise. The TelCove Managed IP-PBX Service (MIPBX) provides environmental, transport, monitoring, and maintenance services to support IP-PBX applications for customers who choose to maintain their own dedicated IP-PBX system.   "Ennovative had an easy choice in deploying TelCove`s Network VoIP Service," said TelCove`s southeast regional vice president Joe McCourt in a statement. "As an existing TelCove customer, Ennovative simply swapped out their TelCove analog business lines with our TelCove VoIP solution. In doing so, they gained tremendous flexibility for their telephone services and many added features and functions, while maintaining their business relationship with TelCove, a trusted service provider. They also benefit from much simpler voice service administration and better reporting capabilities, while consolidating their voice and data networks and eliminating usage charges. As Ennovative`s experience indicates, it`s easy to see why so many new and existing TelCove customers are moving to VoIP."
