Hello Bogdan,
you mean openspis to do client auth when sending the call as a
result of a "location" node ?
Yes indeed. I want to filter and forward domain-bound SIP services
and forward that. I'd like to keep it as general as possible, so
others can use it too.
Not following you - location node can only look in the registered
contacts (in the cpl module). So the outcome of a location node is
loading contacts and forwarding to the devices.
Maybe you can detail a bit here.
you can do that by using the uac_auth() from uac module (requires
uac_auth module for credentials)
This is a single secret (or HA1) if I understand the small mod-doc.
Would work when forwarding to a single node under my control, but not
to permit users of a service to setup their own CPL scripts with
arbitrary forwarding and their _own_ passwords, without letting other
users benefit from those passwords too.
you can use as many secrets you want :) - the uac module has as params 3
avps for dynamically passing to the uac_auth() function the username,
realm and passwd to be used for auth - and you can load these values
from DB or whatever.
I suppose then, I would have to modify uac_auth to make it more
flexible, and donate back the code. I could try to do that.
Do stop me if I'm saying something stupid :)
see above :)
do you get a DTD validation error ? or how are the examples rejected ?
When I send it the first example in RFC 3880 I get
| 500 Bad CPL file
| Log:: Error: CPL script doesn't respect CPL grammar
|
This seems to be caused by an indent before<?xml...?>
because when I remove that indentation, I get
| 500 Bad CPL file
| Log:: Error: CPL script is not a valid XML document
|
Then, when I change the RFC-compliant text
<cpl xmlns="urn:ietf:params:xml:ns:cpl"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="urn:ietf:params:xml:ns:cpl
cpl.xsd ">
into the minimalistic form
<cpl>
It finally gets accepted with
| 200 OK
|
It may be due to the use of an XML Schema in the RFC and a DTD in
OpenSIPS...?
It may be - i remember some hard times making DTD validation working
with libxml2 while using namespaces... Simply skip that for the moment :).
Regards,
Bogdan
