The CTI mode for the phone is still yet not completed and is probably why you are having this issue. Kindly keep up to date with our blog posts with regards to changes made and full functionality. Bear in mind that this is still a BETA and several implementation are yet to be put in place.
Thanks Matt.
Understanding v12 is still BETA... its good we are able to discuss things like this to know if we are all experiencng something or just specific software setups have an issue. Especially when the manual has specific steps to make changes... and those are not leading us down the correct road.
Looking forward to v12 becoming more stable and released for production use.
That was a very annoying thing till I have found the solution by trial and error:
1. You are using 3CXPhone V12 as the SIP softphone
What to do :
1. Go to your Extension Settings
2. Put in an Email Address
3. Go to 3CXPhone Tab
4. Choose Default Phone USE : Inbuilt Softphone
5. Choose Start up Screen : Presence
Now go to the Extensions main screen:
1. Click on the required extension
2. Click on (Send Welcome Email)
3. Download and Run the Config File
Enjoy , The trick is setting 3CXPHone to : Inbuilt Softphone/ Presence and having this in the provision file
