A new enterprise management suite is also part of release 5, providing graphical topology views of the network, inventory details, network health monitoring and voice quality assessment. Enterprise Manager will replace the previous Ops Manager, which was limited to monitoring only Mitel ICP and SX PBXes; the new suite monitors Mitel adjunct application servers as well. The suite also will accept plug-ins from other vendors, including Viola Networks Inc.s NetAlly, for additional monitoring and voice quality assessment. Entry-level pricing for Mitel Enterprise Manager is roughly $5,000, Johnson said. Release 5 has also added hot desking: the ability to log into any IP phone and have it download all of ones contacts and user preferences. It has added to its Q.SIG support, the standard used by PBX makers to interoperate at a base level of features. The enhancement adds the ability to automatically redial busy numbers as soon as they are free, or redial unanswered numbers as soon as the system detects activity and a hang-up on that line.And among the new security features is triple-DES encryption for calls traversing the public Internet. AES encryption is slated for an upcoming release. "Weve continued to harden against denial-of-service and intrusion attacks and virus protection," Johnson said. "Were based on the VxWorks operating system, which has upgraded its OS to ward off direct attacks, and were keeping it as well as our call-control software up to date for that."Finally, Mitel has sweetened its offer by including a basic level of unified messaging. The included UM will present voice mails within e-mail inboxes and will be enabled via mailbox license. It also will run music-on-hold, multilevel auto attendant (as in, connecting calls to departments and then employees within departments), and forwarding incoming calls to off-site phones or mobile phones. On the higher UM end, Mitel has an OEM relationship with Esna Technologies Inc.,and it markets its full-featured messaging system as Mitel Messenging Server 6510.
