Wow! I had no idea so many people cared. Thank you!
Here was the deal:
1. AT&T tested the line, they said it was fine
2. Local phone company said the line was 'fine', but we insisted they do more than just talk. The attached a t-bird and viola! Extreme packet loss in Geneva on the smart jack
3. They replace the smart jack with an identical model...we put the station back in stereo and holy shit the problem is back.
4. They check cable and run more tests, problem is with the smart jack again.
5. Vendor meeting to get everyone on the same page. Local phone company says its AT&T, AT&T says its my Moseley Starlink
6. More tests are done, and the replace the smart jack with a much older version...problem disappears. I can now send full stereo audio and Ethernet without issues.
In the end, all three parties have just gone through a learning curve. We now have contact numbers and technicians who understand how/why our equipment works with theirs.
Problem solved...and on to the next one.
P.S. I love bottles with purple bags on them...they are my favorite flavor
