Create a Mutating Tunnel to bypass Voip blocking btw ios/android apps & (Asteriks/Freeswitch) -- 2

We already have a Voipswitch developed on Astericks and also FreeSwitch and we also have IOS and Android apps that delivers Voip calling from any country. We experience Voip blockage in some countries eg UAE and Brazil etc. We need you to be able to use Kamailio to build or create a tunnel or add mediator server that will act like a proxy that will bypass the voip blockages put by those countries . Thereby allowing voip calls to flow to and from our softswitch without loosing call quality or volume. The solution must also mutate so that if the country notices our service and blocks our app or IP. Your solution will mutate or change IP so that customers will always be able to make his or her international calls without blockages All softswitch functions must work after deploying your voip antiblock solution. Note that you need to know how to achieve this solution using Kamailio
