I’m upgrading an asterisk 1.2 to 1.4
Which files should i copy to the 1.4 server?
Should i copy all the folders that asterisk uses?
I did only copy sip.conf; that allows me to register with my softclients, but i cant call between them.
Hi
If its a vanila asterisk, firstly read the release and upgrade note, then make the changes to your dialplan so its complient, I would then set up a spare PC with 1.4 on it load you complete /etc/asterisk directory and then see if it load ans what complains 
by looking through the logfile then clean up all the errors and there you go…

Well you should know as its your system.
But for example is it bristuffed, patched has freepbx or another gui

I just did download the asterisk 1.6 version, and installed it on my centos 5.2 system.
