I need help setting up carrierroute using the rewrite prefix and the strip function. It
seem like every time I use the Rewrite Prfix function the carrierroute module will rewrite
the prefix, but then I don't get certain reply messages on kamailio. At least from
what I can see on the log.
INFO:carrierroute:cr_do_route: uri 5555550001 was rewritten to
sip:0115555550001@aslab.commx.net, carrier 1, domain 10
INFO:carrierroute:rewrite_uri_recursor: URI or prefix tree nodes empty, empty rule list
INFO:carrierroute:cr_do_route: rewrite_uri_recursor doesn't complete, uri
0115555550001, carrier 1, domain 10
Is this normal behavior? I also noticed that some messages coming back from the host are
not being processed by kamailio. For example on this particular call I purposely get a
604 from the server. The thing is I can't process a failure route for this message,
because kamailio doesn't see is, even though it is being sent back to the server.
Also when I use the Strip function is looks like carrierroute does a second lookup on the
route table. In the example below I am calling a number using the prefix 551... The route
table is below.
+----+---------+--------+--------------+-------+------+------+-------+-----------------+----------------+----------------+------------------------+

It will also help if there was complete routing example using carrierroute v 1.5.0, since
the one in the wiki is outdated. Thanks.

Hi Carlos,
did i understand you correctly, the message request URI is correctly
rewritten, and can also be relayed with e.g. t_relay? But you don't get any/
some replies (for this requests) back on your server?

INFO:carrierroute:cr_do_route: rewrite_uri_recursor doesn't

Is this normal behavior? I also noticed that some messages coming back
from the host are not being processed by kamailio. For example on this
particular call I purposely get a 604 from the server.
The first log message says that the msg R-URI was correctly rewritten. The
second one means that cr was not able to find a match for the URI, either
because of an empty URI, or an empty routing tree for this case. The third
one is an information that the message was not routed.
The cr module doesn't generate any SIP failures itselfs, so the 604 should be
come from your config or an upstream server.
The thing is I
can't process a failure route for this message, because kamailio doesn't
see is, even though it is being sent back to the server.
Have you checked if the reply actually arrive on kamailio? Do you arm the
correct failure route with t_on_failure in your config before sending out the
request?
Also when I use the Strip function is looks like
carrierroute does a second
lookup on the route table. In the example below I am calling a number using
the prefix 551... The route table is below.
Usage of the strip functionality don't cause a second route lookup, i think.

Do you relay the call after the first rewrite? Perhaps there is some routing

Yes sir that is correct. I have a b2bua and the requests are forwarded to it, this causes
kamailio to loose track of the state of the call.

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.
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.

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.

I am only following the few examples that I can find. The message is missing something,
the second route is the failure route. But in your reply it seems to be truncated. I wish
there was a few implementation examples that we could follow, I really like the
carrierroute vs lcr.

Back to your config: you've two cr_route calls in them, in route[11]. Another

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.
I am only following the few examples that I can find. The message is
missing something, the second route is the failure route. But in your
reply it seems to be truncated. I wish there was a few implementation
examples that we could follow, I really like the carrierroute vs lcr.

Thanks for your reply!! I see what you are saying.

Hm, then the example you've found is wrong. I guess you already read the
README and found the examples. There are some other examples in the test/
directory in the source tree. Take a look to test/26.cfg, which shows a
normal routing with failure_route. The 26.sh shows the DB setup for this
case.
Back to your config: you've two cr_route calls in them, in route[11]. Another
one is in the failure_route[11]. You need to remove one of the cr_route calls
in route[11], double rewrite is not valid.

perhaps you forgot to enable record-routing, so
kamailio is removed from
the path?
No I do use record-route, like I said, it only failes after a re-write.
Hi Carlos,
ok, strange.
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");

I need help setting up carrierroute using the rewrite

carrierroute module will rewrite the prefix, but then I don't get certain
reply messages on kamailio. At least from what I can see on the log.
Hi Carlos,
did i understand you correctly, the message request URI is correctly
rewritten, and can also be relayed with e.g. t_relay? But you don't get any/
some replies (for this requests) back on your server?
INFO:carrierroute:cr_do_route: uri 5555550001 was
rewritten to
sip:0115555550001@aslab.commx.net, carrier 1, domain 10
INFO:carrierroute:rewrite_uri_recursor: URI or prefix tree nodes empty,
empty rule list
INFO:carrierroute:cr_do_route: rewrite_uri_recursor doesn't
complete, uri 0115555550001, carrier 1, domain 10
Is this normal behavior? I also noticed that some messages coming back
from the host are not being processed by kamailio. For example on this
particular call I purposely get a 604 from the server.
The first log message says that the msg R-URI was correctly rewritten. The
second one means that cr was not able to find a match for the URI, either
because of an empty URI, or an empty routing tree for this case. The third
one is an information that the message was not routed.
The cr module doesn't generate any SIP failures itselfs, so the 604 should be
come from your config or an upstream server.
The thing is I
can't process a failure route for this message, because kamailio doesn't
see is, even though it is being sent back to the server.
Have you checked if the reply actually arrive on kamailio? Do you arm the
correct failure route with t_on_failure in your config before sending out the
request?
Also when I use the Strip function is looks like
carrierroute does a second
lookup on the route table. In the example below I am calling a number using
the prefix 551... The route table is below.
Usage of the strip functionality don't cause a second route lookup, i think.
It does... See my earlier reply.

Log for that call
INFO:carrierroute:cr_do_route: uri 5515555550004 was rewritten to
sip:15555550004@10.10.10.1, carrier 1, domain 1
The URI was correctly stripped.
INFO:carrierroute:cr_do_route: uri 15555550004 was
rewritten to
sip:15555550004@10.10.10.1, carrier 1, domain 1
This is strange. Does this both logs belong to one INVITE?
Yes this is all one invite.
Carrier found!! ("1",
"131.226.0.144", "15555550004", "15555550004",
"COMMX-LD");
Now please note that if I remove route id 31 then the call log looks like
it is below:
INFO:carrierroute:cr_do_route: uri 5515555550004 was rewritten to
sip:15555550004@10.10.10.1, carrier 1, domain 1
INFO:carrierroute:rewrite_uri_recursor: URI or prefix tree nodes empty,
empty rule list INFO:carrierroute:cr_do_route: rewrite_uri_recursor doesn't
complete, uri 15555550004, carrier 1, domain 1
Do you relay the call after the first rewrite? Perhaps there is some routing
loop, that causes the second lookup.
I rewrites and then looks up again. If I don’t have a route for the re-written prefix then
it relays the call but I don’t see any replies after that.
It will also help if there was complete routing
example using carrierroute
v 1.5.0, since the one in the wiki is outdated. Thanks.
Can you give the URL of the wiki do you refer to?
Sure is referenced by the Kamailio Docu wiki at:
