Hi fellows.
We are in trouble with this "deceitful" error. I mean, errors. Look at RURI. Our
proxy receive this "thing". We have a number there! Sometimes, this number is
shown within the word REGISTER, like that: "REGI:34846:STER". We can rewrite the
URI, but Openser doesnt understand the method "REGI:34846:STER". Second error:
Via header. The REGISTER is showing the NAT_DEVICE_IP instead UA_IP. And this VoIP isnt
behind any VoIP device! So, "who" are changing it? "Who" can does it?
Is possible that some "device" between UA and our proxy change the headers
intentionaly?
This kind of problem had been happening some months ago and began at the same day to VoIPs
were different regions of the country (Brazil). We would like to know with someone already
has face it.
Thank you all.
