We have a user who claims they see an incoming call on their screen and when they pick it up it is gone. In the logs, it says their phone was busy and the call went to voicemail. Their extension is setup to go to voicemail after 20 seconds when no answer or when busy. But, he also has option to accept more than 1 call at the same time. When we talk to the incoming caller, they say they got transferred to a "Setup Voicemail" prompt. Anyone else experience this ? we are on v11 SP1.
