How do IP-PBXs work with other applications, including legacy applications?
The Vertical platform can host both custom and third-party applications, managed locally or remotely. Vertical also provides a simple, script-based development environment for custom applications to address specific customer needs. The Vertical solution can also be tightly integrated into backend applications and databases enabling companies the ability to provide new customer-facing applications like inventory look-up. Other vendors require additional servers (dedicated for some applications), again adding to the cost of the solution.
