Have a Viking PA-2A paging unit to hookup to a Avaya IP Office Rls 9.1, was told I also need a Bogen Interface unit for this to work ???

No, if you can make that thing do a page port or have a spare analog trunk port. I have no idea what Bogen unit they are talking about.

Thanks for the reply Hal

It says I need a Bogen VMT-1A Line input / output matching transformer to be connected across the tip & Ring of a analog port on the combo card, keeping the port in a constant "Off Hook" condition, ????

You'd need the Bogen interface if you were using a Bogen amplifier, probably to provide talk battery or to match impedance. Read the product info for the Viking equipment here. It should be all you need.

WMT1A keeps 600Ohm resistance on the line so the IP Office knows it is there.
If you dont want to use that, you have to prove to the system there is a device on that port. So you would need to have an analog device plugged in, and off-hook, when the IPOS reboots every time. Then you can plug in your paging.

If the system reboots without the off-hook device plugged in, the port will not work.

Who is this "it" anyway?

Thanks for the feedback guys, Hal, Mongo & JB ( it ) was a tech support group i was using for a few years, it seems they have made a lot of cutbacks and people have left, the tech support they have now, seems to shoot from the hip alot, if & when they get back to you, but again, thanks for your help and support, and Happy Holidays to all
