I may be missing something obvious, but any suggestions could help...Have a 6408+ with bridged apprs. for another users phone. cordless headset(plantronics cs50) connected to first user. When first user selects dial tone from headset it picks up the bridged appr.line not the headsets phone line? phone settings seem correct for headset. plantronics support was no help..they mentioned a priority line on phone settings but,found no such setting.
