The IP Office system can support DECT handsets through the attachment of a Avaya Wireless DECT system. The following capacity considerations apply:

• Extensions

  Each Avaya Wireless DECT system supports an extension maximum of:

  • 1500/750 on Linux-based IP Office primary/secondary servers when using Avaya Wireless DECT R5/R4 firmware respectively.

  • 750 on Linux-based expansion servers.

  • 384 on IP500 V2 servers including expansion servers.

  • The DECT extension capacity must be within the overall extension capacity of the individual IP Office system and the whole IP Office solution, including non-DECT extensions.

• Base Stations

  A maximum of 1000 DECT base stations connected through a master base station.

  • A maximum of 128 of those can be digital base stations connected through IP DECT Digital Gateways (up to 8 IP DECT Digital Gateways, each supporting up to 16 digital base stations).

  • IP and digital base stations can connect to the same master base station.

• System Directory

  Up to 2000 directory entries from the IP Office system.
