[Asterisk-Users] Transfer caller but on no answer, return to transferee...

[Lenny Tropiano / asterisk.org Mailing list]

So Asterisk gurus out there, is there a nice clean way in the dialplan
to determine if the caller is coming from a transferred call, and on
the unavailable context in the dial, instead of going to e-mail go 
back to the transferee?  

If anyone has this sort of logic or could spit out an extensions.conf
snippet; I'd be grateful.

Thanks.
