CCM 4.X and Unity 4
Using Extention Mobility. A user want that when he is on a call, if a second Call arrives, caller should get busy tone instead of voicemail. Also the user wants that after he logs out of his phone using EM, that calls goes to Voicemail.
How can i achieve this? already setted busy trigger to 1, Forward Busy internal/external to voicemail. but doesnt meet what he wants.
