[SR-Users] Contact and Record-Route are using Private IP Address- is this correct?

[Samuel F.]

I think that if you want someone to review this you would have to provide a:
- Topology
- Configuration
- PCAP from the Kamailio

Hello Samuel,



I do listen on -

listen=udp:localIP:port advertise externalIP:port

listen=tcp:localIP:port advertise externalIP:port

However, it is the localIP that is being used in contact and record-route.  I do have Asterisk in the mix, could that be what is causing the IP to be local?

Also, what is strange is that some providers are able to use the local IP.



Thank you,

-Steve

I'm assuming you are interfacing with an external party, and then, yes, the external IP should be used for the RR header assuming that party should be able to route to that route.



Furthermore I assume you have multiple interfaces on your machine, in such case you need to set the listen/advertise param:

Hello All,



Contact and Record-Route are using Private IP Address - is this correct? I though the Public IP should be used.  I do not know what setting is causing this to happen.  Does anyone have any ideas?



Thank you,

-Steve
