Key Telephone System
Key systems can be leveraged to support office communications.
Companies that manage their inbound calls by sharing lines across all employees and departments typically find what they need in a traditional key telephone system. And just because these systems are geared toward smaller and mid sized business customers, it doesn't mean they don't provide rich features. CornerStone's solutions deliver the basic functions that allow sharing of voice lines, placing calls on hold, and using intercom calling between employees, but also offer the benefits of features such as voicemail, auto-attendant, caller ID display, call distribution, and the flexibility of supporting IP, digital, or even analog stations. Our many choices of desk phones provide large displays that are easy to read and function keys that let you access features without needing to memorize feature codes.
The typical profile of a business using a key telephone system:
- Up to 30 users
- Single office location
- A majority of voice lines shared among users
