Not sure if this is the right place to put this out there, but I completed migrating from an on-prem IncrediblePBX VM to TheWebMachine’s AWS FreePBX. And in the process have three Adtran 924’s that I no longer need in production. They were in active use and were working fine in conjunction with the IncrediblePBX deployment. Rather than fiddle with them in the AWS FreePBX migration I realized my sites no longer had boatloads of analog lines, so I retired them.
If any of y’all are possibly interested in them, here’s the eBay listing --> https://www.ebay.com/itm/224694420966.
