Triad 1 with the additional cabinet (so that makes it a "2")
IN8020-1 4.15 Basic on the ROM's on the MBP1

Shared office space, 4 port Vodavi Digital Voicemail hung on the wall.

The phones ring daytime at Reception and select other locations, the first 6 lines have night coverage set to 450, and the VM answers those lines with a day or night menu as appropriate, using a time control.

Voicemail for the other lines is accomplished with Preset Call Forward Destinations, ringing for lines 6,7,8 is not assigned for "Night" so they go through ring cycles until the call forward timer kicks in. They also ring at station 100 for those cycles.

The ringing is an annoyance, but I'm trying to figure out if there is an easy enough way to have call coverage for both of these offices as they are actually 1 office, just with special branding on lines 6-8, 9-14 are not so much of an issue, they work fine as is.

Obviously with the time controls set on the VM, I get the line 1-6 greeting if I set ring to 4xx for night mode.

I generally can bend things to my will, but the System/VM interaction on this is just different enough from the others I have worked with to leave me fuzzy.

I am not sure what you are trying to accomplish here, but when I have a need for multiple greetings in order to answer some lines with a custom greeting different than the others I usually ring to a virtual extension that can be forwarded immediately to a greeting or after a timer expires. I program the voice mail subscriber info to have the extension ring directly to a menu and the same for the box and then the caller can go where they want. In other words don't split the vm ports to answer with different greetings, use the internal actions of the voice mail to get where you want to go. The vm is dynamic and all ports can answer all calls and still play custom greetings.

Sorry, I missed some detail.

Yes currently I have it setup so that 6-8 are tagged to mailbox 152, which is a forward to menu 152, the catch is the 4 rings before it answers at night, which are actually ringing on the reception phone.

Well, the Triad is quite old and I don't think it has separate timers for station day forwarding and night forwarding like the newer systems do. You would have to change the ringing assignment in flash 40 and ring directly to the voice mail as opposed to 152 at night. This could be accomplished by night ringing a second virtual number that is all call forwarded to voice mail all the time.

I don't recall that the Triad-2 had virtual stations. The method I remember using was to have an actual unused station port set to immediately forward to voice mail or to have an unused analog port direct ring with C.O. Preset Forward set to 1 second. Then, once the mailbox initially answered, almost anything could be accomplished.

For a handle on call coverage, I would suggest adding a 6-port SLT for those other primary ringing assignments and put call cover for those stations onto the desired phones. With this hardware suggestion, you wouldn't even need a DTMF or ring gen add-on and these boards should be quite cheap today.

Well, the Triad didn't have the virtual id for a station. I was using "virtual" as a generic term, which is not real clear, "unused" is the accurate description.

Lately, I feel "unused". I think I am becoming a generic "virtual" geriatric.

sorry to hijack the post (not!)

Look the question I had when you said virtual is all sorted out before I get back to ask. I have poked through the 3-4 layers of buttons related to a line and haven't seen a second timer. Will dig up the list of stations and assign one with a port but not phone this week and see what that does, I was close to doing that but confused in that I was going to hookup a phone to it.

Finally happened across a solution. Route to a hunt group for night ringing, with 0 or 1 member and a 1 second timeout, overflow to 440 with the extension for the menu as the overflow ID.
