[asterisk-users] attended transfer caller hears ringing after transfer done

[Mitch Claborn]

Asterisk 1.8.10.1~dfsg-1ubuntu1

A calls B.
B answers, intiaites an attendeded transfer to C.
C answers.
B hangs up.
A now hears ringing forever, until the call is terminated.

blind transfer does not have this problem.

What am I missing?
