Plan the installation


Begin the planning phase of the installation by utilizing the data collected. Fill this data into spreadsheets, which can be used during the installation. The call flow will be designed and then the network configuration will be diagrammed.

Extension planning

Extensions are required for most devices on the system. To avoid re-numbering user extensions, it is important to think about the organization and plan for the future. If a single site is all that is required, a three-digit dial plan can be utilized. If multiple sites are required, at least a four-digit plan will be needed.

The only new concept that will be added here is that of a phantom extension. A phantom extension is a typical user extension that does not have a phone registered to it. Phantom extensions can be utilized for general delivery mailboxes and call routing.

The following table can be utilized for planning extension use:

Site Name

User Extensions

Hunt Groups

Call Park Orbits

ACD Queues
