Blues boss Alex McLeish spotted an opportunity and quickly offered the 34-year-old a two-year deal with the guarantee he will be spearheading the club's bid to win promotion back to the Premiership.
Rival clubs were also in the hunt to land Phillips, but the striker said his mind was made up after speaking to McLeish.
"I spoke to the manager and he was very keen for me to join," Phillips told the club's website.
"He explained to me what he is looking for this season and that I am going to be a major part of the club's push for promotion. Plus a big factor for me was that I didn't have to move."
