Connection Problem

I have installed freepbx-2.5.1 and asterisk-1.6.1 successfully in fc8.
And also i could register two users 200 and 201 using X-Lite ip phones.
but when tried to call from 200 to 201 it says “sorry that user is invalid”.

when i have modified /etc/asterisk/extensions_additional.conf mannually as follows

exten => 200,1,Dial(SIP/200,20)
exten => 200,n,Answer
exten => 200,n,Hangup

then it is working fine.

Can any one please guide me how to connect with out modifing the extensions_additional.conf file? whether there is any compatibily problem in versions?

You are not suppose to be modifying those to add in extensions. Let FPBX do it’s job and add extensions for you

You may want to check the write authority on that file/folder. Make sure Asterisk is the owner and not root or Apache

Can you please tell me how can we chek the ownership of Freepbx?

“ls -l” will show ownership. To change, if needed, chown would be the proper command
