I have a asterisk working already which was built by the former admin.
I want to add a new extension.I created a number for my grandscream trough freePBX. and the grandscream can get the extension number from the asterisk and showed it on screen. but it showed ‘not registered’ once I picked up the headphone. and showed ‘403 forbidden’ while I dail to the other extension.
I am just wondering, why it showes ‘not register’ while it got the extension number from asterisk. I mean it can get the number from asterisk,it already got registered,otherwise it can not get the number.
any hint / adversory would be very appreciated.
