Automatic return of transfered call

Hi everyone,

is it possible to achieve that when you transfer inbound call (from outside) to some extension (someone call main number at reception and you transfer that call to someone),if that extension doesnt answer, that call automatically return to you (reception)?
If I just put that every extension upon non-answering end up at reception then every non-answered call from inside
will end up at reception and that would be nightmare for receptionist.

features or SIP?

For at least some blind transfer cases, ${BLINDTRANSFER} is set to link the two sides. You should have a look at the value of this for the failed calls.
