Ok,
you got the easiest way ... :)
thanks !
I used this one :
# callee is behind an ipbx (avp ipbx) ?
if (is_avp_set("$avp(s:callee_ipbx)"))
{
xlog("L_INFO", "-> user is behind an ipbx
($avp(s:callee_ipbx)), set flag ipbx and rewrite request-uri");
setflag(14); # flag IPBX
=> subst_user('/(.*)/$avp(s:callee_ipbx)/');
xlog("L_INFO", "-> verif: to-uri = $tu , request-uri =
$ru");
}
in the debug, result is the same :
Nov 6 11:32:32 ser0 kamailio[6616]: -> user is behind an ipbx (spa9000),
set flag ipbx and rewrite request-uri
Nov 6 11:32:32 ser0 kamailio[6616]: -> verif: to-uri =
sip:0123452001 at sip.720.fr <sip%3A0123452001 at sip.720.fr> , request-uri =
sip:spa9000 at sip.720.fr <sip%3Aspa9000 at sip.720.fr>
you remember to me that the pseudo-variable $rU is R/W too ...
many thanks !
.Sam.
