    I have just moved a customer over to SIP lines, the main trunk number is working fine, but all of the DIDs are getting busy tones when dialed.

    The issue has been resolved. The screenshot I included was actually somebody is France trying to access my system, the address has been blacklisted...... back to the issue, I found that my DIDs contained 7 digits and my SIP provider was only sending 4. Adjusted my DIDs to contain only 4 digits and the issue was resolved.
