I have a legend R.6.1 V.11 that is in the hybrid / pbx mode and all lines are in a pool [70] , now all lines appear on the operators console like they are programmed to do and when a call comes they just P/U the handset to answer the call, my problem is that after I added 4 more lines to that pool now the operator has to physically push the line button that is ringing to answer and to hang -up the line which they never had to before adding the lines .What happened and how can I get that feature back ? any help much appreciated thx J
