IP Office licensing is rather complicated. I’m not going to spend too much time on it but I would like to point out a few rather important details.
The IP Office Basic Edition is a starter-edition of IP Office that only supports one PRI (Up to 64 total trunks with analog and SIP) and up to 9 Auto Attendants. It does not support any applications or IP telephones. It can be configured through a web interface or phone-based administration. Up to 100 telephones are supported on IP Office Basic Edition. Six concurrent connections to embedded voicemail are supported with approximately 25 hours of storage.
IP Office Essential Edition offers more flexibility over the Basic Edition. It supports up to 40 Auto Attendants and 8 PRIs. This version offers the benefit of IP telephony, including One-X Communicator, mobile twinning, and remote worker support. The Essential Edition comes with 2 concurrent voicemail connections and 15 hours of storage. This can be upgraded to 4/20 or 6/25. There is a built-in conference bridge that supports up to 128 simultaneous connections. Up to 64 connections are supported in a single conference call.
An IP Office Preferred license requires the Essential license and adds some additional functionality. Instead of the embedded voicemail Preferred Edition allows the use of Voicemail Pro. This can be on a standalone server or on a Unified Communications Module (UCM). Voicemail Pro adds significant functionality to the IP Office, including unlimited multi-level auto attendants and up to 40 simultaneous VM connections. The amount of storage available for VM Pro depends on the size of the hard drive on the VM server. A good benchmark is that each minute of voice stored will take up about one MB of hard drive space. VM Pro also includes call recording and an enhanced conference bridge. A single IP Office Preferred License can supply VM Pro to multiple sites in a Small Community Network configuration. VM Pro also adds support for web-based voicemail retrieval. The VM Pro server can be installed on a Linux-based or Windows-based server. The UC Module is Linux-based. When installing on a Windows server all Microsoft licensing requirements must be met for the server platform.
IP Office Advanced Edition provides all of the features of the Preferred license and adds a number of contact center features. Advanced Edition supports up to 150 agents and 30 supervisors in a contact center environment. The Advanced Edition can provide access to real-time and historical reporting to manage efficiency. Recording of all calls can be configured with sufficient storage on your server. You can configure your menus to interact with an SQL database to provide a better interactive customer experience or to offer self-serve options. Visual Basic scripting is supported with a Windows-based Advanced Edition server.
In addition to platform licensing you must also have a license for all your IP endpoints and trunks. A basic user (Digital or analog station) does not require a license. Any IP set requires an IP Endpoint License. There are two types of IP endpoint licenses: Avaya or third party. The appropriate license must be purchased for each endpoint. Additional licenses must be purchased for PRI B-channels above the eight that are included with the PRI daughterboard.
Currently license files are provided through http://adi.avaya.com/ but this will eventually be transitioned over to https://plds.avaya.com/
