[OpenSBC] B2BUA not rewriting request URI
Hello,
I'm trying to upgrade our installation of OpenSBC 1.1.4 to version
1.1.5, but I can't seem to figure out how to get it to rewrite the
request URI. I have the "Rewrite Request URI" box checked but it's just
not happening.
Details:
We're using OpenSBC as a B2BUA to connect our Asterisk server to our SIP
provider. Our Asterisk machine resides on a private network. We're
running OpenSBC on another machine which has one interface on the
private network and one interface on the public network. Our setup
looks something like this:
Asterisk <--
private net> OpenSBC <public net--> SIP provider
When we initially set things up, I used version 1.1.4 of OpenSBC, since
that is the latest source tarball linked on the web site. We have
everything working great with this version.
From reading the mailing list archive, I got the impression that 1.1.5
is what we really want to be running, so I checked the source code out
of CVS tonight (I just pulled HEAD, I didn't see any other branches/tags
that looked like what I wanted, is this correct?) I have 1.1.5 compiled
and installed but I can't get it to work. It looks like the new version
is no longer rewriting the request URI.
Asterisk sends out something like this (IPs changed to protect the
innocent):
INVITE sip:18005551212@192.168.0.10 SIP/2.0
OpenSBC version 1.1.4 takes this and sends something like this out to
our SIP provider:
INVITE sip:18005551212@200.1.2.3 SIP/2.0
This is what our SIP provider is expecting and everything works great.
OpenSBC version 1.1.5-2 (checked out today) doesn't rewrite the IP and
sends something like this out instead:
INVITE sip:18005551212@192.168.0.10 SIP/2.0
Our SIP provider responds to this with a 407 and the call fails to complete.
Again, I do have the "Rewrite Request URI" box checked under the "B2BUA
Routes" section of the configuration interface.
I've attached a copy of my opensbc.ini. Can anybody tell me what I'm
doing wrong with regard to rewriting the URI?
