I've been using mod_callcenter in what I can imagine is not the originally intended use case. It's worked so far but now I've run into a problem and being new to FS I've gotten stuck. I originate a call to an extension on another voice system (non FS), and then use Mod_callcenter uuid_standby to keep the agent ready in the queue. I then make an outbound call and put the call into the queue ( like a dialer or click to dial type setup). This all works great, the problem comes when I want to transfer. I've tried uuid-transfer, tried to park the call etc., as soon as I try this the outbound call drops. The closest I've gotten is to use att_xfer directly to an extension on the other non FS voice system, this works fine. The problem is if I want to transfer to another queue, which is a function I definitely want. Any assistance would be greatly appreciated.
