HOW DO DISA AND CALL BACK WORK?
Call Back and DISA work together to allow you to place calls through TalkSwitch when you are away from the office. Call Back provides the capability for the TalkSwitch to call back to a designated telephone number. DISA (Direct Inward System Access) requires password authentication to allow an incoming call, or call-back call, to bridge to an outgoing telephone line or VoIP trunk. Both schemes allow you to access the TalkSwitch and benefit from the company’s calling plans, with telephone companies or VoIP service providers, and reduce roaming charges.
