7.VPS Trunk Service & Automatic Time Mode Notification for Incoming Call*
Multiple tenants can share a single VPS; each tenant does not require a dedicated VPS port. If the destination of the incoming trunk call is a VM (DPT) group, the PBX sends the VPS trunk group number and time mode (day/lunch/break/night) of the tenant ( 
2.2.4 Time Service) assigned for the call to the VPS. Therefore the VPS can send the assigned message (company greeting) to the caller. Corresponding VPS trunk group number and tenant number are determined by the setting of the incoming trunk call as follows:
a)DIL/TIE: the setting of each trunk port ( 
1.1.1.2 Direct In Line (DIL), 1.28.1 TIE Line Service)
b)DID/DDI: the setting of each location number for DID/DDI ( 
1.1.1.3 Direct Inward Dialling (DID)/Direct Dialling In (DDI))
c)MSN: the setting of each MSN ( 
1.1.1.4 Multiple Subscriber Number (MSN) Ringing Service)
[Example] For DID Calls:
Each location number can have its VPS trunk group number (message number) and tenant number.
