FreePBX 2.6.0 defaults to refusing anonymous SIP calls.  If you enable
inbound anonymous calls, it includes only the "from-trunk" context, making
it behave like a standard incoming over over a configured trunk.  If you've
configured FreePBX to allow outgoing calls from the trunk context, you have
larger problems in general.
