Hello. We are using (MCD 4.1 SP2 - SW load: 10.1.2.13)We have external hot desking users that have been having issues with Mid-Call features (invoking them inadvertently i.e. placing calls on hold..handing off etc.). I changed the system options form to utilize Feature Access Codes and set them in the FAC form. Everything is working well with the exception of invoking the features i.e. Hold, Hold Retrieve, Handoff etc. I have FAC's for each feature and have all users with the appropriate COS. I am not able to invoke these features. Any suggestions as to what I might be missing? When we were using Mid-Call features we were able to put callers on hold, handoff etc. Thank you!!
