[OpenSER-Users] Linux variant recommendation?

We have done some basic development using OpenSER, now it is time to build a production system. The first application will be an alias_db application (using mySQL) to do call forwarding. We do expect to develop other applications in the future. We have some brand new Dell server class boxes for the project so we have plenty of hardware capacity. We do not have a lot of UNIX knowledge, so we would like to take advantage of a package based environment. What variant of Linux would you recommend for this system?
