HI ALL;
 
 
i have the following network:
 
 
 
cisco ata(invalid ip)---------------------ser+rtpproxy(valid ip)-----------------------UA(valid ip)
 
 
i want to call from ATA to another UA with valid ip
 
 
1) Have i use rtpproxy inorder to work my ATA behind nat?
 
2) I have problem registering my ATA at ser , and making calls
 
 
Can anybody send the desired ser.cfg file?????????
