We have a 5600 with Enterprise Messaging. We also use Xarios for Hotdesking. No Answer IC calls are not being forwarded to voicemail when an agent is logged in. Yes, both the physical extension and phantom device have forwarding paths to voicemail. Yes, both are set to forward IC as well as CO calls. I wish it were that easy. When the agent is not logged in, the IC call is immediately forwarded to voicemail. Anyone have any ideas?
