Hi. ext 100,101 & 102 are in a ring group (800). 3CX v9 SP5a. Extensions Cisco SPA501G. 3 x SIP trunks If their is an incoming call, all 3 phones ring. User (ie ext 100) answers the phone, their is then another incoming call, ext 101 & 102 will ring but not 100. So 100 finishes his call and wants to answer the new incoming call but his phone does not ring. Am I correct in thinking that if he dials *20* he can pickup the incoming call? Is their a way of setting up a spare button on the Cisco SPA501G's so that you just press press it to pickup 'ring group 800'. Thanks in adavance.
