[OpenSIPS-Users] Wrong IP when relaying REGISTER to Asterisk

[Web Support]

Bogdan,

I am using the fix_nated_contact() because if I don't, it tries to register
with the private IP of the device on my network... still not the public IP
of it.

Perhaps I'm attacking this the wrong way, maybe you can clarify for me what
I actually want to do. The end I'm trying to reach is to secure my dialtone
via TLS, as Asterisk (1.4 due to PBXware) doesn't support it. 

After reading forums, mailing lists, googling non-stop... everything is
starting to blur. Maybe you can outline for me the steps I need to put into
place to make this work. As mentioned before, ideally I would like Asterisk
to acknowledge the UACs as their public IPs, not the OpenSIPS server, as I'm
putting together a multi-tenanted environment. My understanding is that I
would:

1. Register UAC through OpenSIPS via TLS.
2. Registration is relayed to Asterisk, Asterisk would see the public IP of
the UAC.
3. INVITES made from a registered UAC would in turn relay through OpenSIPS
to Asterisk, which would send it to the destination directly, bypassing
OpenSIPS. 

Is this logic flawed?

Tyler,

The script logic (for REGISTER) is a bit broken - you authenticate the 
REGISTER, you save it locally, send a reply to UAC and then relay the 
REGISTER to asterisk; which will send you back a reply, so you will end 
up with 2 replies back to UAC :)

Regarding the contact part, I see you are using the fix_nated_contact()  
function - this is the only function that seams to modify the CT hdr.  
To validate this assumption, try commenting the function and run again.

Regards,
Bogdan
