VM Service
1.Accessing a Mailbox
The PBX sends special messages to the VPS to indicate which mailbox should be accessed (Follow- on ID).
2.FWD to a Mailbox of the VPS
An extension user can set his or her calls to be forwarded to the VPS (
1.3.1.2 Call Forwarding (FWD)). When a call is received at the extension, the PBX sends the extension's mailbox number to the VPS, and the VPS answers the call with the appropriate OGM (e.g., "Hi, I'm out of the office today...").

3.Intercept Routing to a Mailbox of the VPS
Outside (CO) line calls via DISA (
1.15.6 Direct Inward System Access (DISA)) can be programmed to be automatically redirected to an extension user's mailbox when the extension user does not or cannot answer them (
1.1.1.2 Intercept Routing). The VPS can answer the call with an OGM (e.g., "I can't take your call now...") and callers can leave messages in the mailbox. In order to use this feature, a voice mail extension number must be assigned as the intercept destination for the original destination extension that received the call (
CO Line 
DISA Intercept Mode [507]).
