Voice Messaging Interface (VMI) Port Capabilities
VMI ports use switchhook flashes for Hold, Transfer, Conference, and Drop in
the same way single-line telephones do. VMI ports also have the ability to perform
transfer redirection, to respond to far-end disconnect, and, in the case of
integrated VMI ports only, to send call information and mark a port in or out
of service. The following sections describe these capabilities. Both integrated
and generic VMI ports can perform trunk-to-trunk transfer.
