Avaya IP Office V3

V3 IP Office

Version 3 systems preceeded the IP500 system (v4 & v5) and this version is still being supported. The 54xx and 56xx-series desk telephones were introduced in 2005 and we provide advice and recommendations on upgrading these legacy systems. Many components and devices are compatible with the new IP500 systems, meaning that attractive and cost-effective upgrade options are available. For a support contract quote, click here.
