Have a couple of Polycom 331 registered with an Elastix server and FreePBX has the incall blind transfer (##) and incall attended transfer (*2) enabled. But when I try making a call and pressing *2 or ## while on call nothing happens. I tried transfering the call using the Polycom transfer buttons and that worked but the feature codes don't. Is there anything I am missing. (FYI: It's elastix 1.6 and updated using yum).
