Using freepbx without dahdi

hi guys, newbie here

will freepbx and asterisk run properly even without using dahdi? because were only going to use softphone, currently i manage to install freepbx and asterisk on ubuntu server “incoming calls” are good it’s just that im getting “all circuits are busy now” on “outbound calls” and im trying to figure out if it’s because we dont have dahdi installed as stated on the installation guide i followed

Any thoughts?

Thanks

What version and install method are you using? What type of trunking? I have multiple installs that use SIP trunking without any analog hardware. In these cases the dummy DAHDI driver is loaded to provide timing.

im currently have asterisk 1.8.4.4 and the latest version of freepbx

i just followed this guidelines and upgrade the system thru freepbx admin
