I have quite a few OBi202 devices that have been auto-updated to the latest FW 3.2.2 (Build: 5898EX) and are now having issues sending faxes. We did not have this issue sending faxes until this firmware update. We are able to receive faxes on these devices without issue, it is only the sending of faxes that we are having issues with.
For example, I try to fax to a specific number using one of the OBi202 devices and the call just hangs up after connection, or we get error stating that the line is busy or no answer, however if we go to our fax machine that is attached to a plain old telephone line and send to the same number, it goes through without issue.
