Big features; big capacities
IVX S-Class combines multiple
first-rate, feature-rich
systems into one
tightly integrated unit:
- Business phone system
- Full-featured voice mail/automated attendant
- Messages-on-hold
- Enhanced Caller ID*
- Optional VIP and VIP Professional communications management tools
- Optional IVX Presence Management
IVX S-Class handles a configuration of up to 16 × 32 × 8.** And, when your business grows beyond this capacity, IVX S-Class can migrate to a larger ESI system which uses the same ESI phones, minimizing upgrade costs and retraining.
