Hi Miha,

OpenSIPS returns in the 200 OK for a REGISTER all the valid registrations for that user (for all the devices the user may have).

I guess your user has 2 registrations, so the 200 OK will report back both of them. You can check via "opensipsctl ul show"

Hi Miha,

When you handle REGISTER requests (from behind NAT) most probably you use fix_nated_contact() instead of fix_nated_register().

Hello

i need one info.
I have one phone behind NAT and it is registered on OpenSIPS. IN register packet, which is send to OpenSIPS I can see contact: "sip:[email protected]:5060;transport=UDP"

and let says that the public ip for this device is xxx.xxx.xxx.xxx.


When opensips sends INVITE it send to right public ip and right port (source ip and source port generated by router). The issue is this: Invite is like: "sip:[email protected]:5060;transport=UDP" and this request is then fw to this UAC behind router. The UAC replays to this INVITE with 404 Not found as it is waiting to receive the same URI which was written in contact (the userpart is ok, put the ip is public, not private and this is the issue).From what I can see in RFC this is the case.


Till now Idid not have any issues with this, but now I found first phone which replays with 404 and from RFC point of view there should be private ip request :) . So is there anything I can do :)?


tnx
miha
