Netscape).

Voicemail Pro Licenses
The actual number of ports available on Voicemail Pro is controlled by license keys entered
through IP Office Manager. For more information, see Voicemail Pro Licenses.
The Voicemail Pro license enables 4 ports.
Additional Voicemail Pro licenses can be added to enable further ports up to the
maximum shown above.
Data Channels
The IP Office may support a higher number of data channels. The figures shown above are the
maximum that can be simultaneously used for voicemail operation.
Note
The IP Office telephone system uses data channels for functions other that voicemail
connections. This may reduce the number of data channels available for voicemail.
VoIP/VCM Channels
Though linked to the IP Office via a LAN connection, voicemail does not use VoIP VCM
channels. The Voicemail Server is seen as a device on the IP Office's TDM telephony interface.
Calls to/from voicemail involving non-IP trunks and extensions do not use VCM channels.
Calls to/from voicemail from IP trunks and extensions do use a VCM channel.
