System is V12 and 3CXPhone (softphone) is V12. Is it possible and if so how. Thanks. In V10 Phone System and V6 3CXPhone (softphone) I could be registered SIMULTANEOUSLY as more than 1 extension and all I had to do was to click on the top right hand area of V6 3CXPhone to cycle thru the extensions that were registered. Now in V12 3CXPhone I cannot register multiple exts. Yes I can register another extension by going into Settings > Accounts etc and then register another but that takes too long and is not practical for busy staff.
