Tandem whit remote extension and set supervision?

[gnuttisch]

Hi

I have a 4028 whit tandem to a remote extension. On the main set in the tandem config (4028) I set a set supervision whit long ring on a third set.

When the third set is called, the main set of the tandem coupler only rings, not the remote extension. To get the tandem also to ring when the third set is called, I have to set up an set supervision on the remote extension also.
Is this a bug or by design?

I have also testes whit a GAP+ device and it behaves the same as the remote extension.

Regards..

tandem is for incoming when called with the principal number both sets will ring (and in case of calling the clip is principal one) , if you call the second set of tandem, the principal will not ring , so same for supervision you should creat set suprvision key in each sets of tandem because in some cases th set could supervise differents sets
