[Asterisk-Users] Transfer of incoming call from external to internal number

[Paul Goodyear]

When I place a call on my softphone to a external number the call is
placed, when I click transfer, dial internal extrention (e.g. 202)
then hit transfer again, the call is transfered to the 202 extention
fine.

However, when the other way Internal call comes in, extension 201
answers, and transfer to extension 202 the call is ended at 201 but
202 does not ring, the caller on the external line just hears nothing
and the call is lost internally.
