a)If the VPS is answering all incoming calls:
Trunk Mode—Use System Programs [414] (Day Mode), [415] (Night Mode), [416] (Lunch Mode) to set each trunk to "DIL" mode, and assign the first extension of the Voice Mail hunt group as the destination for calls received on each trunk. The PBX will allow incoming trunk calls to hunt only if the trunks are DIL to the first port of the hunt group. Lines programmed as "Normal" do not hunt.
b)If the VPS is only answering calls not answered by the operator (Operator Backup):
Flexible Ringing Assignment—For each trunk, use System Programs [408] (Day Mode), [409] (Night Mode), and [410] (Lunch Mode) to enable ringing at the operator's extension (jack).
Delayed Ringing Assignment—To give the operator time to answer the call before the VPS picks up, we recommend setting the delay to a few seconds for each extension connected to the VPS. Set a different delay time for each extension connected to the VPS. Use System Programs [411] (Day Mode), [412] (Night Mode), and [413] (Lunch Mode).
Trunk Mode—Set the mode for each trunk to "Normal". Use System Programs [414] (Day Mode), [415] (Night Mode), and [416] (Lunch Mode) to set this parameter.
c)If the VPS is only answering calls not answered by user extensions:
Flexible Ringing Assignment—For each trunk, use System Programs [408] (Day Mode), [409] (Night Mode), and [410] (Lunch Mode) to enable ringing on every extension (jack) that you want to have ring.
Delayed Ringing Assignment—To give users time to answer the call before the VPS picks up, we recommend setting the delay to a few seconds for each extension connected to the VPS. Set a different delay time for each extension connected to the VPS. Use System Programs [411] (Day Mode), [412] (Night Mode), and [413] (Lunch Mode).
Trunk Mode—Set the mode for each trunk to "Normal". Use System Programs [414] (Day Mode), [415] (Night Mode), and [416] (Lunch Mode) to set this parameter.
