I see you opened a ticket for this recently. That may be the best way to work this issue. However, if you can recreate the issue and get a copy of the swlog I would be happy to look through it. It would be best if you can delete the current version of the log right before the test, recreate the issue, copy and paste the swlog file in the same folder, and rename the copy to something else (ex: issue.txt). It would help if you included caller id information and all numbers/extensions involved in the call at the top of the file in a description so we can track things easier. After you have that condensed copy of the log you can submit to our FTP server with the instructions below.
Open Internet Explorer web browser on their PC
Type the following URL: ftp://ftp.adtran.com
Press the Alt key, click View, and then click Open FTP Site in Windows Explorer
Double-click the "Incoming" folder
Drag and drop files from PC into the Internet Explorer window
Reply to this post with the exact filenames used so we can retrieve the files
After reviewing the case it appears this issue was related to the licencing. I am going to go ahead and mark this thread as answered. If there is any additional information you would like to provide that may help others who come across this thread feel free to post a reply.
