Installed the latest 3CX CRM Integration. WIndows 7-64bit Outlook 2013 3CX v12.0.37098.738 SP 6.1 CRM installs with no problems and is connected to outlook 2013 stating the plug-in is working fine. I'm able to see the 3CX option when trying to make a call. The problem comes in when I actually try to make a phone call using the 3CX option. This is the error message. An error occurred trying to make outbound call to xxx-xxx-xxxx Cannot create channel sink to connect to URL '//CallNotifierServiceProvider''. An appropriate channel has probably not been registered. Any assistance would be appreciated.
