DECT assistant ringing for two main sets, how to change this

[feltel]

Hello, we have a OmniPCX Enterprise R9.0 PBX and I´m trying to reprogram it. We have two main sets (ext. 150 and 151; both IP 4028 sets) which are twinned to one DECT set (Mobile Reflexes 200) both (ext. 233).

I´m trying to programm the PBX so that ext. 151 doesn´t ring anymore on this DECT set. I found (in mgr > Users > Decent hierarchy > Prog Keys) that there is a 2nd multi-line key programmed with directory number A150 resp. A151 on both main sets which is unique among our other main sets. Trying to delete this key leads to "OBJECT -1: Key No.: directory number used as assistant", but I cannot find the menu entry where I can change the setting.

I think this key used for call 233 - check in this key must be declared another key from this set, where declared key with number 233. You need to delete this key first.
about ring - check - declared in set parameters "tandem"? Or may be you have on 150 and 151 "set supervision 233" key with ring.

If I understand you correctly you have to delete the set supervision key for set 151 on set 233.
Because you wrote "so that ext. 151 doesn´t ring anymore on this DECT set."
I assume the DECT 233 is supervising the set 151.
However you can post the results of:
readkey mcdu=150
readkey mcdu=151
readkey mcdu=233
And of course you can chech the field "Tandem" in the user parameters.
