Yes sir that is correct. I have a b2bua and the

Hi Carlos,
perhaps you forgot to enable record-routing, so kamailio is removed from the
path?
Only happens when I strip a number or rewrite the
prefix. All other cr
calls are processed fine. Now if I add the prefix to the table this works
fine... For example, I dial prefix 54011 to select carrier A, carrier A
wants to see only CC NXXX XXXX from me, so I strip 5 digits to send the
number, than I see this condition. If I add the CC prefix to the table,
then CR module does a second look up and correctly routes the call.
Ok, but normally it should work just fine with only one lookup.
Dial 54011 53 2339 2339 sent to carrier A 53 2339
2339... you can imagine
how my tables are going to look if I have to add to routes per carrier...
at least for those carriers that are not assigning me a prefix. Routing
login is below.
route [11]{
xlog("L_INFO", "INFO: entering carrierroute routine\n");
cr_user_carrier("$fd", "$fd", "$avp(s:carrier)");
$avp(s:domain)=$fd;
setflag(16);
Ok.
if (!cr_route("$avp(s:carrier)",
"$avp(s:domain)", "$rU", "$rU",
"call_id", "$avp(s:host)")) {
sl_send_reply("480", "Temporarily
Unavailable");
setflag(2);
exit;
}
if (cr_route("$avp(s:carrier)", "$avp(s:domain)",
"$rU", "$rU",
"call_id", "$avp(s:host)")) {
xlog("L_INFO","Carrier found!!
(\"$avp(s:carrier)\",
\"$avp(s:domain)\", \"$rU\", \"$rU\",
\"$avp(s:host)\");\n");
force_rtp_proxy("o");
Why do you use the routing function two times? I can't imagine a good reason
for this. If you want to log the success, just do this after the first
cr_route. And also move all your logic in the second if case after the first
one. If the lookup in the first cr_route fails then your routing tables are
not correct.
Cheers,
