[44net] New to amprnet have some questions

Hello all, So I have been assigned a block of IPs and have successfully created a gateway. I am able to pass traffic trough it as expected and it works as one would expect. However... My intended use case for amprnet includes a lot of VOIP traffic, which as we all know is heavily dependent on latency and bandwidth. I am currrently utilizing the IPIP tunnel approach to connect my gateway into the system. My questions are, 1. If I deploy my VOIP services on 44Net with my current configuration, what are the pitfalls? 2. If I announce my gateway via BGP will my throughput then be limited to uscd gateway, or will it be based on my connection speed? 3. I know some vpn capabilities have been introduced into the system, I presume that my connection will then be rated based on the connection at the VPN server location. Thank you so much! I appreciate the opportunity given here to learn and expand my knowledge. 73, de KC2IDB
