For our analog phones in the warehouse we use a Welltech 3232s gateway currently, prior to a few months back we used the 2424s gateway but this model no longer exists. The problem, in 3cx there is not an option to add a 3232s, you need to go to Welltech.com and download their .xml file and install it on your 3cx server and this in turn will place the 3232s in the dropdown when adding a new device. However, the defect is this, something continues to update on 3cx system that erases the 3232s.fxs.xml file from the 3cx server. When this happens, if you attempt to back into the FXS node to view the configurations of the 3232s device, KA-BOOM, big ugly error. PLEASE 3cx, add the 3232s option to your updates. Please use file "welltech-wellgate-3232s.fxs.xml" and place it to "C:\ProgramData\3CX\Instance1\Data\Http\Templates\fxs" folder. After this, you can go to FXS/DECT page, add the 3232s device, provision it and start the testing.
