Only if the dial plan actually gets enough information to set the
accountcode, which at least historically wasn't the case for Asterisk.
In 1.2.x, you couldn't in the dialplan tell if a call went A->B or
A->C(SIP redirect)->B. BLINDXFER didn't get set correctly in all
cases.

The alternative is to use the built-in accountcode from sip.conf; I
haven't verified how well that actually works. It won't work if you
need to distinguish two different phones behind a SIP trunk, but I
don't think anything can, so we can forget about that case.
