You can use the sipgetheader() application. If you pass a call to 
asterisk, the field "To" in the SIP header stay as originally dialed. 
So, with

sipgetheader(or_To=To)
Cut(or_To,or_To,:,2)
Cut(or_To,or_To,@,1)

in your dialplan, you can get the original dialed number.

with the cut function you can cut the "sip:" and the "@domain.asd" 
substrings.
