Hello there, I have installed Elastix 1.6-12 and all incoming and outgoing calls are functioning. Yesterday we need to change the default gateway of the server. I changed it through the GNOME interface, after changing I then restart the service of astrisk. The restart seems never end and since then all the calls stopped. All I can hear from outgoing is "All circuits are busy now, try again later". I can ping outside ip address and www.google.com still but the elastix just not lose the connection to the outside world. What could cause the problem? Need to fix configuration? Appreciate your help.
