What is the maximum number of trunks that IPO can support based on configuration?

The maximum number of trunks that IP Office (IPO) can support is indeed up to 300 trunks, depending on the version and model of the IPO being used. This capacity can vary significantly based on the specific system architecture and the licensing agreements in place for individual deployments.

In particular, the architectural capabilities of the IP Office platform allow for different configurations that can expand trunk capacity, such as considering various protocols and trunk types (like SIP trunks or digital trunks). Different models of the IPO, such as the Control Unit and the Server Editions, may also have different limits, contributing to this variation.

Understanding the flexibility of the IPO system regarding trunk capacity is crucial for planning and deploying IP telephony solutions effectively. This answer encapsulates the scalability features of IP Office and emphasizes the importance of model and version considerations in determining maximum trunk support.
