I have a customer that wants to use VMC to host their VM's. Several of their VM's handle some type of VoIP workload traffic. The VoIP VM's are public facing VM's without a NAT, currently on vCD w/NSX-V (not sure which exact version). I'm not a VoiP expert by any means but from my understanding, NAT'ing doesn't pass VoIP or SIP type traffic. In VMC/NSX-T, a public IP is required to be routed through the CGW using NAT. My question is if anyone is using VMC for VoIP traffic, how are they handling the NAT configuration?
I have neither none experience on this but I do know we did some tests with partners/customers based on different VoIP vendors and that worked well. AFAIK most of issues could be with latency between users and VoIP systems so of course, the closest you are, the better it is.
I would say it worth a test with a PoC.
