I have setup a call queue in IPCC Express. I have 2 DNs setup on their phones, one is their primary DN and the other is the DN that is associated with the ICD in CCM. Everything seems to be working ok except when an agent is logged into the queue, and they use their phone to dial out on their primary extension, it logs them out of the queue. And when they finish a call from the queue, it logs them out. Any suggestions on where to start with this?
