Im trying to use openser as a Proxy for different interfaces in one box I have tried almos averithing to make it work properly but for some reason I cant.

 

Here is my setup and I hope someone can helpme  or guide me in the right way.

 

 

 

 

One Linux-OpenSer box with 4 netcards

 

1 Has a public ip

2 Has a 192.168.23.10 ip

3 Has a 10.254.10.240 ip

4 Is not being used

 

I want to be able to make calls from the ATAs in all the different networks, but the fact is that as it is now I cant, I want to know if I have to set up multiple media proxies or rtpproxy if I have to use a proxy dispatcher  or not.

 

This is my configuration file

As you can see I use different starting numbers for the ATA for each of the interfaces, I tested using only one mediaproxy listening to 127.0.0.1 but I have tried a lot of configurations, all the clients register perfectly but cant seem to call one another exept the ones that are on the same interface.

 

Im using fedora core 3 with openser 0.95 mediaproxy 1.42

 

Hope any one can help me or point me the way to do this of if its not viable or cant be done.

 

Thanks a lot for your kind help

 

Yours truly
