Yes.

Anyway, I think I found a workaround using a second Dial statement :
after the first Dial times out, I check if another call (the one launched
after receiving the 302 Moved Temporarily message) have been started and
interrupted by the first Dial timer.
If positive, then another Dial is triggered with appropriate settings (new
timeout and and extension values).
