Second alternative is 1, which I understand is the default and doesn't push to the voicemail number as there is no number set and everything is set to 'normal'.
They do have the Micollab client, but not the ability to manage status, it seems to happen when they set the status to Do Not Disturb or Out of the Office but I thought in the back end when setting up the Call Forwarding I changed it to be the group and not the voicemail number, this is what is reverting back.
Is there any way to lock this so that it doesn't change back to voicemail?
Thanks :-)
