I had not picked anything out yet, other than asterisk/freepbx and the hardware I am running on currently. The rest is all up in the air based on what would be a best fit for the situation.
Phones ideally would be PoE with an extra port in back for a PC connection, with 2-3 line capabilities. Not sure what other features to look for, honestly.
Currently the FreePBX I have is 2.7.0-6_centos5, what is what is the best method for upgrading?
