AFC Wimbledon have made Mark Phillips their fifth summer signing.
The former Southend defender was snapped up by Dons manager Neal Ardley, who was also a team-mate of Phillips at Millwall.
Neal told their official website that the 32-year-old, who ended last season on loan at Aldershot due to contractual reasons, knows the league well and they are hopeful he can add to the quality of their squad.
He said: "It's been exciting times with the club growing rapidly and I'm very happy to now be a part of it. It's a great club and I jumped at the chance of signing."
