I've justed installed 3CX Phone System Version 5.1.4128.0 and this seems to still be an issue. The call forwarding doesn't work as long as the call is coming from an outside line.
The log is:
16:24:57.213 Call::Terminate [CM503008]: Call(17): Call is terminated
16:24:57.193 LineCfg::getInboundTarget [CM503011]: Inbound office hours' rule for LN:10000 forwards to DN:200

16:24:46.898 Line:

16:24:46.668 LineCfg::getInboundTarget [CM503011]: Inbound office hours' rule for LN:10000 forwards to DN:200
The setup is:
Line 10000 forwards to extension 200. Extension 200 is forwarding to extension 300 which again alsways forwards to my cell phone. When I do an internal call from extension 200 to 300 it works well (my cell phone is ringing).
Just to be specific: I've also tried to forward line 10000 to extension 300, but that doesn't work either.
I hope this can be fixed soon (or somebody can give me a tip on what I'm doing wrong), because I kind of need the new functionality in version 5.
