Aastra's new MX-ONE(TM) IP-PBX Version 3 optimizes business communications with extended system capacity for up to 50,000 end-users, standardized management and web-based tools.

One key enhancement in this version is the introduction of support for the session initiation protocol (SIP) for IP telephony, in both terminals and trunking for networked systems. Along with deploying SIP, the integration towards Microsoft Live Communication Server, making it possible for MS Office users to look up and dial people directly from any MS Office document or application is another significant step towards unified communications. MX-ONE allows businesses to integrate messaging and multimedia services with business class voice communications and also enables wireless telephony over WiFi. Security has also been enhanced on all areas of management accesses, and media encryption has been introduced.
