Have you really explored this area? Laws are very strict in EU / Europe, US, China, India.. There are no loophole against court order... and mainly for regulatory approvals, if you don't have that capability, your application will be rejected. I work in Telecom enviroment and your response makes me believe that you haven't really explored this area.
We also have people on our team who work in telecommunications and compliance. We know about the strict laws in some places, and about the legal use of encrypted VOiP in some areas as opposed to others. We can and will manage the same rules and regulations that everyone else deals with. Thank you for your interest.
