lineOpen failed [0xFFFFFFFF8000004B] #39
Description
Hi, we have been using our TAPI driver on Windows 2012 server - no problems whatsoever. Recently we upgraded to Windows 2019 OS, and ever since we have been getting the following error at random times , we are struggling to determine the cause of this.
Does anyone have a suggestion at to what this error code relates to?
