Hello,
I'm trying to make outbound proxy for my network using OpenSER.
Currently I've configured OpenSER as sip registrar/rtpproxy and it works
fine even with NAT traversal. The problem is that I don't how shuould I
reconfigure my config to make it work as outbound proxy. I've tried many
changes with no results. The first problem is how to correctly handle
the register method. My config is based on:
http://siprouter.onsip.org/doc/gettingstarted/ch08s02.html
Can anyone help me?
Don't know exactly your problems, but for an Outbound proxy just deny
REGISTER if the URI is not local (or maybe not in your case), and ask
ALWAYS for authentication for INVITE, MESSAGE and other messages if the
URI is not local, so just your local uses can use the proxy as outbound
proxy (if not it would be an open-relay).
About the REGISTER, I just can't imagine a case when a REGISTER goes via
outbound proxy. ¿?
I think that I've made mistake naming my scenario as OB proxy. Here's
how it looks like:
UA (private IP) <-> NAT (public IP-1) <--> (public IP-2) SIP/RTP proxy
(public IP-2) <--> (public IP-3) SIP Reg / Gateway
The other scenario is to set my proxy behind NAT with UA and then it
would look like:
UA (private IP) <-> (private IP) SIP/RTP proxy (public IP-1) <-->
(public IP-2) SIP Reg / Gateway
UA's are configured to register at third party SIP Reg (VoIP service
provider) and they are also configured to use my proxy as OB proxy. What
I wan't to achieve is to close SIP / RTP traffic (using my proxy) if it
is local and relay it to third party gateway if it is external.
Let me understand the problem. So the UAC's are registered in the external
provider and in the internal proxy? maybe handling this is the problem you
have?
Yes that is the problem. The config which I've attached with my previous
mail was to test if the NAT traversal section works ok. Now I've to
change it to handle the described scenario.
