Cisco Unity Express (CUE), is the module that supports the Voicemail and Auto Attendant operations, among other applications, in the UC500.
As of version 3.0, the maximum number of sessions is as follows:
- A maximum of six (6) simultaneous Audio Sessions using RTP (Real Time Protocol). For UC 560, the number of RTP sessions is 12.
- These 6 or 12 sessions can be any combination of the different Telephony User Interface (TUI) functions, namely:
AA - Auto Attendant
VM - Voicemail
VVW - VoiceView
Live Record
- If there are 6 or 12 concurrent TUI sessions, there can be only three or six (depending on the UC 500 model) VVE browsing sessions (no audio).
- Maximum of 20 IMAP sessions.
- For AA operation, the sessions are freed after a call transfer/handoff, leaving it available for additional calls.
