[Users] RTPProxy and SER, Multiple Interface Server

Hello All. After investigating quite a while about this issue I'm kind of desperate now, I will appreciate your help on this. I have a OpenSER Server with multiple interfaces, I'm able to handle all the SIP packets with the multi homed enabled. Now the part that I'm having real trouble with is the RTP audio streams. After struggling with MediaProxy I finally started using RTPProxy for this, since it has bridge mode available. Now the problem is that I have more than one network to connect audio from, so the internal and external configuration is not enough for me. So my questions are: 1.-Can I have RTPProxy Bridge mode working for all the interfaces in my server? 2.-Can I have more than one RTPProxy socket available for each of the multiple interfaces I'm connecting in order to have the audio working, so each route will use the proxy of their own network? 3.-If #2 is true, is this where the force_socket and force_rtp_proxy functions play a role in my configuration? Please help!! Thanks you so much in advance Gerardo Amaya
