[Freeswitch-users] Call Forwarding from phone

Hello, I have a configuration (dialplan?) question. One of my users used the "call forward" button on his sip phone. The phone is directly registered to FS. The forwarded calls fail. It looks like the phone is sending a "redirect" message to FS, but then the call is then not getting routed correctly through FS. So, the call is dropped. Is there something specific I need to configure to account for possible call forwarding from phones?? Thanks, -Noah
