Thanks for your reply !
When I put strict_route at the place of loose_route, i have an error. (Module
missing).
Ser version is : 0.8.12.
What can i modifie to apply strict routing only?

I want to disable "loose routing" on
IPTEL.
What can I write in my configuration file to stop loose routing?
I assume you have to exchange the function "loose_route()"with
"strict_route()" in you ser.cfg.
I have disable this line:
modparam("rr", "enable_full_lr", 1) but the
UA(With RFC 3261) use always loose routing.
Of course, this only modifies the "lr"-parameter in the routing header.

Hi,
this is not an SER problem. Loose routing is basically done in the end
devices. All you can control on the server is whether the server should be
in the signalling proxy chain (record_route()) and whether you want to
process route-header-fields (loose_route()) or forward to the final
destinanation directly (t_relay() without loose_route()).
As loose routing is the standard routing procedure as defined in RFC3261,
strict routing is obsolete.
With strict routing, you will get a lot of problems for the reverse
signalling from the target to the source, because you will not have
sufficient routing information in most cases.
Regards,
Martin

this is not an SER problem. Loose routing is basically
done in the end
devices. All you can control on the server is whether the server should be
in the signalling proxy chain (record_route()) and whether you want to
process route-header-fields (loose_route()) or forward to the final
destinanation directly (t_relay() without loose_route()).
Sorry, this is not correct. The routing mechanism (loose or strict) has to
be followed by SIP proxies. Look at RFC 3261 para 16.6 step 6 where the
strict routing behavior is defined:
"If the copy contains a Route header field, the proxy MUST inspect the URI
in its first value. If that URI does not contain an lr parameter, the proxy
MUST ..."
But I expect that this behaviour is implemented in SER. In previous versions
of SER there was the possibility to force SER to do only strict routing.
This has been disabled now and in my previous comment I looked into the
documentation which is not updated accordingly and still mentions the
function strict_route(). But looking into the code of rr_mod.c you can read
as a comment:
"I do not want people to use strict routing so it is disabled by default,
you should always use loose routing, if you really need strict routing then
you can replace the last zeroes with REQUEST_ROUTE to enable strict_route
and record_route_strict. Don't do that unless you know what you are really
doing!"
As loose routing is the standard routing procedure as
defined in RFC3261,
strict routing is obsolete.
To be precise: strict routing is deprecated. If you have a strict router in
a SIP router chain the proxy forwarding to a strict router has to be aware
of this fact as mentioned above.

(Module missing). Ser version is : 0.8.12.
What can I modify to apply strict routing only?
Sorry I did not check that this previous function has been eliminated. But
following the comment in rr_mod.c there is a possibility to force SER into
strict routing (see above) behavior. Look into the code. Than you also have
to use "record_route_strict" instead of "record_route".
But I have heavy doubts that this will help your problems. Do you really
know why you want to fall back to a deprecated routing behavior?

Use record_route_strict instead of record_route.
