Maybe you can use the "g" option in the first Dial(...) and proceed in
the dial plan with the second Dial(...)

g - Proceed with dialplan execution at the next priority in the current
extension if the destination channel hangs up.

Example:

exten => 1234,1,Dial(SIP/deskphone,120,g)
same => n,Dial(SIP/cordlessphone)
same => n,Hangup()

Extension 1234 dials a deskphone. If "deskphone" answer... bla bla
bla... and after "deskphone" hangs up, the "cordlessphone" is dialed.
