Yes Ed, we run into that all the time on the Partners.

They dedect fax CNG, but if the other waits to hear the fax it won't work.

That's why we all hate fax switches!!

Larry,
No I'm using the KSU's fax detect circuit, It's just when it times out on the detect circuit it than rings the phone (attendant in this case) than after the phone rings the pre designated time it than goes to the VM as programmed in pre-set call forward.

Vodavi suggest adjusting the CO line levels up or down to see if that cures it. I don't think that will do it as levels to a milliwatt are good, but I will try as suggested. They also stated it may just be a bad unit so I'll let ya know what happens. FYI: I'm just going to adjust levels, I'm not going to reset cause I know that cures it for awhile.

Bill, I have to tell you that I have rarely seen adjustments in CO line levels ever cure something like this. It's their shoot from the hip solution for a lot of things. I've only seen this actually help with VERY few voice mail volume issues.

I don't mean to sound pessimistic, but since your problem is sporadic, it's going to be really hard to keep adjusting it up or down and actually know if it really had any effect. I think the only way to know for sure what's happening is to run an event trace either with a laptop or via a modem. The problem with that is you would just have to leave the trace running (possibly for days) which would require a laptop be left on-site or tie up one of their lines (and yours) throughout this process.

I will check some of the recent tech support bulletins that have been issued to see if there's anything addressed. We get them monthly and I usually don't pay much attention to the STS items because there usually aren't any. If I find anything, I will let you know.

I am tending to lean toward the possibility of a bad KSU. I know that you and I aren't Rockefellers, so if you want to PM me, we can discuss some possible replacement options we can work with.

Thanks again Ed, I have to agree, but must try. As far as KSU goes, it's under warranty so no problem there.

i know i've seen the station co handset volume cause issue on faxes before. Have you tried turning up the co handset volume on the slt port?

If not make an outside call from your but set or fax handset and when the call is connected flash it dial 638 then dial 0 thru 9(0 being the lowest volume) and then you will here a confirmation tone.

Thanks oobie, not getting that far. The fax detect never transfers the call to slt extention assigned when not working.

FYI: This seems to be corrected. What I did was start one at a time removing any feature associated with the CO line that points to the fax detect circuit. The last thing (or combination of?) that seems to have corrected this problem was I changed the CO line ringing assignment to the main admin phone ( CO line associated w/fax detect) to days only (comes default d/n). I had previously determined that the fax detect would work flawlessly until put manually into night mode. After it failed it would not work again until I'd done a system reset. Hope this saves someone else some grief. I could go back and start putting things back to see if it was a combination of things, but I've already spent enough time on this trouble that can't happen (per Vodavi).

Well worked fine for over a month an a half, now it's back to it's old tricks. Monday I'm removing everything associated with the 2nd line, not that there's much left, and I'm sure it will fail again. Then I'll call Vodavi for a new KSU, since no one else has seen this trouble it must just be a defective fax detect unit on the KSU. Just wanted to update y'all.
