Did you change the IP address of your GoAutoDial server?

[jack_decent]

Yes i change IP Adress .
Goto autodial Server IP Address shows my public IP not Private.
What should i do ?

[williamconley]

if you changed the ip address of your server, you must run the admin update server ip script in /usr/share/astguiclient.

[jack_decent]

yes i was run update_server ip but still same ..

[williamconley]

did you reboot?

can you dial 8600060?

Have you modified your extensions.conf after installation?
