Aastra 5i Series Expansion Modules Offer increased Call Control and Flexibility
The two Aastra 5i Series expansion modules are designed to increase the power and flexibility of the 5i Series SIP telephones. Up to three modules can be used with either the 55i, 57i or 57i CT telephone to create a powerful, feature rich console option. Modules share power and signaling with the phone, eliminating the need for additional wiring.
Designed for receptionists, administrative assistants, call center agents, power users, and executives who need to monitor and manage a large volume of calls on a regular basis, the 5i Series Expansion Modules provide an intelligent choice for all Enterprise IP environments
