Hi,

For the blind call transfers, the specification says:
"No resumption is possible; as soon as the call connects, the platform
throws a telephone.disconnect.transfer. The interpreter disconnects from the
session and continues execution (if anything remains to execute) but cannot
regain control of the call. The caller and callee remain connected in a
conversation."
The "as soon as the call connects" raises the question - what if the call
does not connect (network congestion, called party does not answer, called
party is busy etc.)?
Since session resumption is not possible, is the original call then simply
dropped? What should be the expected (ideally graceful) behavior of the
implementation platform 
if a blind transfer does not connect? One could play an announcement, for
instance.
 
Thanks,
Ranjan
