This router-based platform supports voicemail and integrated messaging. More information on
CUE can be found in
Chapter 5,
“IOS IP Telephony Skills.”
■
Cisco Unity Connection:
Based on a Linux server, this platform supports voicemail and integrated messaging.
■
Cisco Unity:
Based on Windows Server, this platform provides voicemail and integrated/unified messaging.
Cisco Unity Connection supports local message storage and supports active/active redundancy and directory synchronization. Other
features include speech recognition, VPIM support, Cisco Fax server support, SMS message notification, and secure messaging.
Unity integrates with Cisco CUCM and a variety of legacy PBX systems. It can also integrate with other Unity systems and more
traditional voicemail solutions. The capability to integrate with PBX and voicemail systems allows a relatively smooth transition to IP
telephony.
Depending on the specific release, Unity can be installed on either a Windows 2000 or 2003 server, and it uses either Microsoft
Exchange or Lotus Domino as its message store. Note, however, that Lotus Domino is not supported in Cisco Unity 8.0.
