Do you have any additional devices on this line
that you are trying fax detect circuit on?
(adsl/dsl)??

No. Right now after system reset it's working again, but this isn't right and a customer shouldn't have to put up with it.

Agree,I would try new KSU.

Thanks for the input STSE. If anyone else has heard of this problem I'd sure like to hear it and the fix of course. I'm sure it's the KSU, but would be nice to have some backup when I call Vodavi. I've never had to replace one yet so don't know how it will go.

Just wanted to add this. Per the customer last time it failed they received a fax and immediately after that fax the phone rang on the fax detect line and it was another fax. It than wouldn't work again until system reset.

I would not rule out call ID card as it bridges with co trk ckt.

Regardless,there is only one way to cure this
eliminate the KSU by replacing it.

We are Installers, not Engineers.

Unfiltered DSL line can give your CNG detect
ckt. problems at times.

Before you replace KSU have you reinitialized it

No, this was a new install and system was initialized when installed. I will let Vodavi make that call since I'm pretty sure I've got a bad fax detect circuit. I have already talked to Vodavi and they have never heard of the problem and they could only think it may be a defective KSU. This is one drawback to having everything on one pack, but I'm sure they know that. Thanks for the post and welcome to the board.

Called Vodavi, they feel it's a bad KSU also. Since I have no spare they are sending me a KSU so I can send this one in for warranty work, they are being very fair about the new KSU. Just wanted to fill y'all in.

:bang:

I went through hoops with one customer who wanted this feature enabled. It just doesn't work properly, the problem is that when enable it answers the call and waits a preset (short or long) ammount of time for an initial handshake from the calling fax machine and if the machine doesn't give it then it let's the fax go through to the normal ring assignment. So if the machine that is calling is waiting for a handshake from the machine being called and doesn't initiate, the call fails and the feature doesn't work. Two months on 1.5 hour round trips to finally figure that out. Ugh. Recommend to the customer that they keep their fax line outside of the system.

CNG is getting to the fax detect. It just quits detecting until system reset, than it will work awhile again. Even Vodavi admits this is a defect in the fax detect circuit and since no one else has heard of this problem I don't think it's rampant. New KSU on the way.
