Hello,in FreePBX GUI i was able to set access code on trunk to enabling users making external call,
In Asterisk i ve making a search to be able to do same thing,the only thing i ve noticed is by "Pattern Match" or a prefix "9" or whatever in front of the external number... The need is let user compose the number then enable the call by access code like 1234 for example.
Let me know your thought.
Thanks !
