I am running Outlook 2010 RTM and am having issues with the Outlook CRM integration. I'm running W7 64b. The 3CX Assistant and SIP phone work just fine. I inistalled and am running the assistant with Administrator rights. When I launch the 3CX Assistant I get the following error: An error occured registering channel for call notifications. Application can not continue executing. Value cannot be null. Parameter name: ip I get the same error when exiting the Assistant. I realize that you may not be finished with the Outlook 2010 build. If not when is that expected?
