[OpenSER-Users] Problem in REGISTER with "Route" (I don't want to use "alias" in conf file)

Hi, I've multidomain OpenSer and I want the possibility of adding new domains
without having to write in conf file and restart OpenSer, so I use "domain"
module and functions. It works fine.
The problem is that WengoPhone includes a "Route" in the REGISTER so it is
matches in "loose_route" and creates an infinite loop:
-------------------------------------------
U 2007/09/12 11:00:47.770226 212.121.235.18:1029 -> 88.95.0.210:5060

etc etc...
-------------------------------------------
A developer of WengoPhone said me that this "Route" header is not necessary
but still valid, and that I can solve it by adding:
alias=sip.domain.org
But I don't want to write in conf file for each new added domain, and I don't
want to restart OpenSer when it.
I'm thinking in change:
if (loose_route()) {
by
if (loose_route() && method!="REGISTER") {
but it doesn't seem very ellegatn solution.
How could I solve it? Thanks for any help.

Humm, I could add each domain to /etc/resolv.conf so it works, but it is just
valid for DNS A type... what about DNS SRV SIP?

Hi!
This is a known limitation with openser - loose_route does not import
the domains from domain module.
Maybe we already have it on the feature request list - but if not,
please submit it on the feature request tracker

Yes, ok.
I've found a work around that is adding the domains in "/etc/hosts", but
that
just valid for DNS A registry, what about a SRV registry?

Ok, I'll do.

if your proxy has hostname myproxy.foo.bar and it is serving domain
company.com, then srv entry for that domain looks like
_sip._udp.company.com. IN SRV 0 0 5060 myproxy.foo.bar.
if wengo phone then puts company.com in route header instead of
myproxy.foo.bar, you should report a bug or switch to a better sip ua.

i thought that route header includes list of proxies that the request
should visit, not domains the request should visit:
20.34 Route
The Route header field is used to force routing for a request through
the listed set of proxies. Examples of the use of the Route header field
are in Section 16.12.1.
Example:
Route: <sip:bigbox3.site3.atlanta.com;lr>,<sip:server10.biloxi.com;lr>
so there should be no need to add aliases for each domain your proxy is
serving (unless you want your proxy to have a separate hostname for each
of its domains).

Yes, but note what Klaus Darilion said:

The problem is just in "loose_route()" function. So I've open a bug/wish for
that:

But what I mean is that if my OpenSer is has as local domains (in "domain"
table):
domain1.org
domain2.org
A DNS type A or SRV of those domain should give us the IP of OpenSer, so
finally the proxy = the domain.
So if WengoPhones includes a "Route: domain1.org" in REGISTER then it'll do
a
DNS query (SRV or A) for "domain1.org" and it will get OpenSer IP.
So, what is the difference?
Thanks for your replies.

Ops, I didn't see your reply in Sourceforge:
"this request is invalid. route header contains hostnames or host
addresses, not domains."
That convinces me ;)

I think "Route" header should be canonical hostname and not the SIP domain:
In "SIP Forum"'s SIPconnect program to get SIP compliant devices and
services
we can read:
"SIP Proxy Servers MUST use canonical hostnames in any 'Via:' and/or
'Route:'
SIP header field that it inserts in the SIP message.":
http://www.zoomerang.com/web/SharedResults/SharedResultsSurveyResultsPage.a…
(step 15)
So if that is true then OpenSer behaviour is correct and there is a bug in
oSIP stack because it shouldn't add a "Route" header with SIP domain value
in
REGISTER messages. Could anyone confirm this in order to report the bug to
oSIP developers?

Yes, sure I looked for them before asking in the list.
The point is that I don't understand what they are for.
$du - reference to destination uri
$ru - reference to request's URI
What does "reference to destination uri" mean? what is "destination
uri"? it
shows me "null" in any case.

If loose_route() returns true, a destination uri ($du) is set according
to the first Route header. $dd refers to the domain part of this uri.
So if there's a destination uri resulting from a Route header, you can
check its domain using is_domain_local() and thereby distinguish whether
the domain is served by your proxy.

I understand but can't get it working:
if (loose_route()) {
xlog("L_INFO", "loose_route()\n");
xlog("L_INFO", "Route = $hdr(Route)\n");
xlog("L_INFO", "du = $du -- dd = $dd -- ds = $ds\n");
But in the ACK or re-INVITE I just see:
loose_route()
Route = <sip:86.92.0.210;lr=on;ftag=zxmjg;dialog-id=326.db350534>
du = <null> -- dd = <null> -- ds = <null>
Why these 3 variables ($du, $dd, $ds) are <null> ?
So if there's a destination uri resulting from a
Route header, you can
check its domain using is_domain_local() and thereby distinguish whether
the domain is served by your proxy.
Yes, the idea is good.
