Capacity Planning

Last Updated : Aug 08, 2025 |

When designing a solution using a Linux-based IP Office primary server, many aspects need to be considered for capacity. These include:

  • IP Office Subscription, IP Office Select or IP Office Server Edition deployment

  • Maximum extension, and user capacity required; both per server and solution

  • Maximum anticipated site/node capacity

  • Maximum trunk capacity

  • Hunt group quantity, size and location

  • The total concurrent VoIP call capacity

  • Call media destination location and type; both intermediate and final

  • Direct/indirect/secure VoIP media

  • Conference, and recording capacity

  • Multi-site Network link capacities

  • Call Destination

  • IP Infrastructure & VoIP QoS

  • Trunk utilization and call traffic profile

  • Resilience and Failover requirements

  • Available licenses

All should be assessed as one factor may limit another.

  • Unless otherwise stated, R240 and R260 servers capacities are equivalent.
