so this weekend i was going to upgrade my server from 1.3-2 to the new release. here are my concerns. i have a sangoma A102 using a T1/E1 for my voice. currently i am using a zap trunk "ZAP/g0". when i upgrade, what do i need to do? do i have to add a new trunk in freepbx? i am a little confused so help me out please. i am sure i need to rerun the wanpipe diver setup as well right? thanks for all the help.
