Anyone has faced this problem? Any solution? Your help will be greatly appriciated.

Thanks

Do you have extension 1001 defined and does the credentials in the extension match your phone?

I have similar problem, my outgoing calls are being dropped after less than 30 seconds.
Below is the error i get. Please assist.
