You are trying to use Bonjour for the wrong purpose, what you try to achieve is meant to fail in a large number of cases and each case depends on the way NAT works of the sip service providers have configured their infra (B2B or Proxy mode). The fact that it works sometimes for what you want to achieve does not mean that it will work by some magic trick in all cases. It does not.

Do not use Bonjour for calling outside of your LAN and expect it to work, it does not because of NAT and there is nothing you or anyone else can do about it. 

Is like gravity, you can only observe it but cannot escape it.
