Definition - What does Mobile Centrex mean?
Mobile centrex is a telecommunications service that allows customers to link a mobile phone to a private branch exchange (PBX) for seamless mobility in communications. The service can be delivered through various means, including VPNs or IP PBX systems.
Techopedia explains Mobile Centrex
Mobile centrex essentially allows users to treat mobile devices as an extension of the office telecom system. The service provides PBX-style features that can be used for processing work orders or doing other kinds of enterprise tasks. Mobile centrex effectively ties a mobile device to an office telecom system in the same way that a conventional PBX system splits one phone line into multiple business lines. With mobile centrex, however, a worker out in the field can answer the phone as if he or she were at a desk in the office.
