[Freeswitch-users] bypass media and media proxy

Hi, I want my server sometimes does media proxy and sometimes bypass media. For example, I have A, B and C. A and B always in same internal network. C is outside. When A call B, I want to bypass media, so that media peer to peer. A call C will be media proxy. I know ICE can do that. But unfortunately, all my endpoint doesn't support ICE. I'm wondering is there anyway to configure this. Thanks
