The Aastra 536M expansion module is designed to increase the power and flexibility of the 5i Series SIP phones. Up to three modules can be used with either the 55i, 57i or 57i CT telephone to create a powerful, feature-rich console option. The 536M module shares power and signaling with the phone, eliminating the need for additional wiring. Intended for receptionists, administrative assistants, call-centre agents, managers and executives who need to monitor and manage a large volume of calls on a regular basis, the 5i Series expansion modules are an intelligent choice for all enterprise IP environments.
