So what happens if you unplug 201?
Or what happens if you only have 201 plugged in?

Same thing when only 201 is connected.

When 201 is not connected, nothing happens,
and when I call 701 or 702 it says line is busy.

Probably happens because 201 is the only station in the 500 group.So this only started when you added the 4COP card? What ring voltage and frequency do you use there?And a co line is 48v when on hook? I still wonder if that card is compatible with your lines? I would be interested to see if you put DT XXX keys for the lines on the phone to see what happens. When you answer that 500 call you said you get silence ,what does the display on the phone show?

When calling the line normally sends
25 Hz and about 90 V
On hook is actually -48v

I know people have baught phones in the US and used them over here..

When answer the call it acts just like i expect it would normally do, and theres another call waiting..

So when you answer this call what is on the display of the phone?

The timer fof the call starts.
The CO line 701 show
And bottom says Konf Page Mute

When I choose the other call - button
It shows next CO number 702 and when I
Choose the first again it shows 703 and then 704 and goes back to 701...

So what if you disconnect the lines from the system? I am trying to see if the card is "ringing in" with these calls or if the trunks are causing it. You don't have 4 trunks connected do you?

I have only one trunk,
That is a ip phone adapter
It works with analog phones

When only the 201 and no trunk is connected it still rings..

And it only happens when the 4 COP
Is installed
