• Auto Attendant
This licence enables the use of the Auto Attendant function and is independent
of other voice mail licences. It means it can also be used in conjunction with ba-
sic voice mail.
Note
In a VoIP environment VoIP channel licences are also required for con-
verting the voice data when using the internal voice mail system.
• Silent Intrusion
This licence is needed for the Silent intrusion feature, which is similar to the Intru-
sion feature. The difference is that the user intruded upon receives neither a vis-
ual nor an acoustic signal of the intrusion. The feature is used mainly in call cen-
tres. One licence is required per system.
• Secure VoIP
This licence allows encrypted VoIP connections with the aid of SRTP (Secure
Real-Time Transport Protocol) and TLS (Transport Layer Security).
