I think I found the problem ..

Looking at my SIP Messages, the VIA and the Contact headers doesnt have my
INVALID IP, it shows me my VALID IP.

But I dont know how to set that, im doing the fixes for nated contacts.





Atenciosamente.

> Hi guys,

> After a long time without using Opensips (almost a year) I tried to

> There's anything else that I could take a look at?
