Hello 3CX Community! I have a weird behavior with the newest 3CX TAP Driver in combination with Windows dial.exe and need some help. My System: OS: Windows 10x64 Softphone: 3CX Phone for Windows (14.0.49169.0) 3CX Plugins (TAPI Driver): Newest version from the Website Tested with different Office Versions: Office 2010 x86 Office 2013 x86 Office 2016 x86 I know there is also a Office Plugin available but I need a working TAPI Driver for use with other Software. 3CX Phone + TAPI Driver without Office Installation: After Dialing a number (tried different number formats) --> Error: Internal error occurred in Phone Dialler. Quit and restart Phone Dialler. Office 2010: Calls out of Outlook works like it should - no problems Office 2013 and 2016: When I dial a Number from my Outlook Adressbook - the dialer opens - when i click on "start call" I get an internal error with the hint to reopen the dialer - after that my office freezes - im also not able to restart the TapiSrv service under services.msc. A complete System reboot is the only solution to continiue working with Outlook. I use the exact same configuration as with the working Office 2010 Installation. It would be very nice if someone has a solution for this problem. Thank you in advance!
