Hi all, i wanna offer VoIP SIP service to uor customers. We have a SER server (working) behind a NAT router (BINTEC) and i have forwarded all UDP traffic to my SER server. I have tested it and registrations work but we are unable to talk togheter. My questions is: there's problems with RTP in this case ? Thanks, Oz -- ------ O-Zone ! www.zerozone.it
