Fwd: Re: Re: [Users] 200OK Contact header field.

[Maciek Kowalski]

It seems that I solved the problem by using record_route_preset("my.domain.net");
Now the message flow is correct.
I don't know why does it make a difference if I use the domain name (which will be resolved to public ip address) or the actual ip address. Every suggestion will be appreciated.

Best regards,

Maciej Kowalski

In this message the Contact header field is set to "192.168.1.5:5060". When user recieves this 200OK it sends ACK to IPaddress 192.168.1.5 (and since he is behind different NAT..the message goes nowhere).
