Call Queues keep calling agents, even when they're in a call

Hi,

We have a call queue setup and have a problem - when agents are in a queue call they still get sent new calls from the queue. This is using round robin or longest idle, with conference mode and presence mode either on or off, happens every time. We've tried all the settings with no change.

The only thing I notice is, unlike normal calls, when an agent answers a queue call their status stays on available. Like the server isn't registering they are on a call, so is sending them a new one.

Everything else is fine, queue calls can be answered on any device, transfer properly etc.

Anyone seen this before? This is a queue using direct routing on a Ribbon SBC1K.

Thanks
