PowerPack is a software key that adds extension and auto attendant capacity and voicemail broadcast to systems:
8 IP extensions
6 remote extensions
11 auto attendants
10 voicemail broadcast groups
Multi-unit systems: Adding a PowerPack to a multi-unit system gives every unit on the network the extra extensions. However, the maximum local extensions on a 4-unit system remains 64. The 11 auto attendants and 10 voicemail broadcasts groups apply to the entire networked system.
All new 400vs-series and 800vs-series systems come with a complimentary PowerPack.
