For those IP Office users out there, Avaya has released the new 5.0 software.

Here’s some of the new stuff:

More phone choices with support for SIP phones and new DECT wireless phones. There are also new enhanced features for mobile “twinning”.

The embedded voice mail gained a “dial by name” directory. Voice Mail Pro has expanded from 30 to 40 ports and integrates with Windows Server 2007. The Unified Messaging Web Access includes controls for callback, get previous and get next messages.

External directories can be obtained from up to three different sources per IP Office. A centralized call log for users and hunt groups is driven by the IP Office, not by the phones. IP Office 500 supports T.38 Fax over SIP. The System Status screen has some new VoIP stats as well. It shows QoS reports for each IP extension along with Packet loss, Jitter and Round Trip Delay info.

32 IP Offices can now be networked together in one SCN. And…. the roadmap has support for Partner phones. That will be huge for many Partner ACS users!
