Finally I used that and all it seems to work well: (in AVP 69 I stored the
new URI to reach)
avp_pushto("$ruri", "$avp(i:69)");
avp_delete("$avp(i:69)/g");
sl_send_reply("302", "Moved Temporarily");
exit;
When I use Ethereal, the 302 message contains:
in From header, the original caller
in To header, the original callee
And in the Contact header the new URI I stored in AVP 69
Thanks for your help

Thanks for the hint and sorry I miss this example.
But unfortunately I have a infinite loop if I use directly the example...
I tried to redirect the call to 101 when 102 is used (100 is making
the
call)
When I used a config file like that:
# rewrite current URI, which is always part of destination ser
rewriteuri("sip:102@christophe.fr");
# append one more URI to the destination ser
append_branch("sip:101@christophe.fr");
# redirect now
sl_send_reply("300", "Redirect");
exit;
=> Infinite loop !
How 'bout this?
# rewrite current URI, which is always part of destination ser
rewriteuri("sip:101@christophe.fr");
# redirect now
sl_send_reply("300", "Redirect");
exit;
-g
Now if I use only:
# append one more URI to the destination ser
append_branch("sip:101@christophe.fr");
# redirect now
sl_send_reply("300", "Redirect");
exit;
=> The call is redirected correctly but if 101 cancel the call if
have a "Call failed: 404 user not found" on the device 100. Is it normal ?
Another point: in the example on the end of each URI, there is ":9". Why ?
Example: append_branch("sip:redirect@siphub.net:9");
And finally: the function append_branch() doesn't seem to accept avp
value ...
Thanks,

If you got OpenSER sources, look into examples directory, you have a
redirect.cfg file. Online, you can browse it via:
http://openser.cvs.sourceforge.net/openser/sip-server/examples/redirect.cfg?
revision=1.2&view=markup

Before to reply a 302, I need to change the contact header in order
to specify the URI of the new callee.
For example A call B, but from the config file I know B wants to
redirect calls to C. So I must specify the URI of user C in the
contact header of the 302 message
In your example, you change only the domain:
A call B(a)test.fr and you change the message to A call B(a)test.com
<mailto:B@test.com>

I don't know if this is right, but:
if(is_method("INVITE"))
{
rewritehostport("test.com");
sl_send_reply("302", "Moved Temporarily"); }
seems to work for me.
I'd try loading some branches if you want more than one item in the
contact header. Just guessing though, I'm usually the recipient of a
302!

Hi,
I checked archive without any result... >From an openSER rule, I
want to create a 302 message if a specific RURI is used.
First I need to change the contact header to specify the URI of the
new callee.
I tried something like that:
avp_printf("$avp(s:100)", "sip:test@christophe.fr
<mailto:test@christophe.fr>;target=$ruri;cause=486;");
avp_pushto("$ct", "$avp(s:100)"); # => error generated on this
line
ERROR:avpops:fixup_pushto_avp: unsupported destination "$ct";
expected $ru,$du,$br
So how can I modify the contact header ?
Just after the update on the contact header I envisaged to use this
function sl_send_reply(302, "Moved Temporarily")
Is it correct ? Is there a better way to 'create' 302 message in
this case ?
I check UAC_REDIRECT module but I don't think I can use it in this
case or perhaps I missed something
Before to use a 302 message I succesfully tested to create a new
INVITE with the $ruri modified correctly. But I would like to
create a 302 message to prevent any problem of authentication.
Thanks,
Christophe
