I have an OS7200 with several iDCS 28 phones, and a couple of daughterboards that create an analog extension off a digital port. Is it possible to configure these SLTs in such a way that they mirror the digital port, like a Partner 18 button phone does, rather than just creating another analog port? I need to have the analog port see and connect to what ever the digital port is doing. So far, I just have an extra extension.

we never had partner 18 buttons in uk

but you could try to mmc740 so when one phone ring so does the other

Here in North America you are looking at mmc 217 Station Pair

I need something a little different.

The secondary analog jack in this case is connected to a radio station console. What I need to happen is the analog port cloning the digital station. If the digital station is off hook on line 7001, I need the analog station to be off hook on line 7001- I have no way to control the analog port via feature codes or any dial codes. It has to act just like the digital station.

Don't think that is possible.
