UAE has weird bans on many VOIP solutions, also VPNs are in a bit grey area - I guess that would make remote work too problematic with the tools they use internaly.
I ran into this while doing work for several companies in Oman, their state telecom provider is in a monopoly position for voice calls, and the VOIP ban is to push business to them.
They had some pretty ridiculous workarounds, like using teamviewer for its voice chat function.
