Gents, I've just opened an account with a SIP provider in The Netherlands. (After a successfull run with XS4all). No have installed Ethereal on the SIP server. However, I get the following. I can't make a call to the outside world. I get the error: 479 We dont accept private IP contacts. When a make a call it identifies as 10.0.1.71. But the RTP is reported correctly. Then when a calls comes in from this voip provider it tries to contact to 10.0.1.71 (instead of my outside IP). It worked fine with XS4all any tips?
