Quick resolution:

Edit registry key to remove FIPS complicancy checking in Windows, not very nice because it affects the entire server.
Set HKLM\System\CurrentControlSet\Control\Lsa\FIPSAlgorithmPolicy to DWORD=0 instead of 1.

Of course, with Group Policy turned on, this flag normally gets reset to "1" when the Active Directory is replicated.

So here is another solution: better one: in the Cassini .config file (normally C:\Program Files\3CX PhoneSystem\Bin\Cassini\UltiDevCassinWebServer2a.exe.config), add the lines in italic-bold below in order to have the entire file look like below:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="PingKeepRunningEverySoMinutes" value="5"/>
</appSettings>
<runtime>
<enforceFIPSPolicy enabled="0"/>
</runtime>
</configuration>
