and then restart kamailio, i receive this error:

I'm using 4.4.4 version

Any hint?

Thank you

On both invites the To field respect the correct information from INVITE
so that the kamailio CDR is working correct.

After that the supplier reply me 503 and call is come back to my kamailio.

LCR modules send the call to second supplier that on this case is my
second box kamailio on another countrie..

Here there is this problem that i signed on RED

The LCR modules make the new INVITE using the original To field and
don't rewrite it like on the first request..

How is that possibile ?


Any idea ?

I never used the LCR module myself, but the documentation mentions that
the module "sets the R-URI and possibly the destination URI". If $du is
set any modification of R-URI is just send to the same destination. The
solution might be:
$ru="sip:error1@errorserver.local";
$du=$null;

Re: [SR-Users] LCR routing, and finaly route to media gateway if not found

In fact, kamailio is out from lcr at this point, no more gateway to try
(all gateways are down).
I just want to send call to a static server for playing sound.

To be more specific, if no gateways are not set on database, a sound must
be played.

Should i change $du and $ru to make it work ?

check if both hostname and ip address are given for the gateway.  if so,
next_gw() also sets destination uri.

[SR-Users] LCR routing, and finaly route to media gateway if not found

[Loic Chabert]

Hello List,

I'm finishing my implementation of LCR with kamailio for outgoing calls but
one use case does not work.
Let me explain:
- I have some sbc for one destination. If one destination fail, kamailio
try to second one etc..
- If no SBC is available for this destination (for exemple, all are down),
i want to send my call to an error server (asterisk), play an error sound.

To accomplish this, i re-write the RURI: "sip:error1@errorserver.local",
and launch RELAY route. But kamailio dont make a DNS query to find IP of
"errorserver.local", only change RURI and try to send to the last LCR
gateway.

I have also try to add a new branch, but same result... Why kamailio do not
make a new DNS query ?

Re: [SR-Users] LCR Module Question

Thanks Both Fred/Juha

System is in production when i have a "free slot" i will check repeating
each rule with lower priority. I think that would work as i expect

Thanks for your tips guys!

Have a nice week

If your rules would be the same for both, then you can add a backup gw
to each rule with lower priority.  You can also use defunct_gw()
function to make failing gws inactive for a period.

If the rules are not the same, then in failure route you would need to
call load_gws() with another lcr id.

[SR-Users] LCR Module Question

[Alberto Sagredo]

Hi

I have it working but i have re-read documentation and do not see how to do
what i need.

I explain it :)

Now i have only one LCR provider and i need to add a backup one.

I do not know if its enough to add under same lcr_id or its better to add
with different one and add several lcr_rule and lcr_rule_target

Acordding to next_gw() function, what is better to be used? In my case. a
primary providers is used and only a backup one for the momment.

Thanks for your help

[SR-Users] LCR prefix based

[Roberto Innaimi]

Hi to all, 

i want to use prefix based LCR routing, but for some reason, something is not 
working as expected. 

Can anyone help me? 

This is the LCR configuration:


#LCR MODULE
loadmodule "lcr.so"

modparam("lcr", "lcr_id_avp", "$avp(s:lcr_id_avp)")
modparam("lcr", "defunct_gw_avp", "$avp(s:defunct_gw_avp)")


route[LCR] {
if (status=="200")
{
  xlog("LCR: Inside the LCR route\n");
}

if(method=="INVITE")
{
  xlog("We got an invite");
  if(!load_gws(1, $rU, $var(caller_uri))) {
    xlog("Couldn't load gateways");
    sl_send_reply("500", "Server Internal Error - Cannot load gateways");
    exit;
  } else {
        xlog("GW Selected '$avp(i:709)'\n");
        xlog("Domain of destination: $dd\n");
        xlog("To URI: $tu\n");
  }

  if(!next_gw()) {
    xlog("Couldn't proceed to next gateway");
    sl_send_reply("503", "Service not available, no gateways found");
    exit;
  } else {
        xlog("Calling the first matched gateway\n");
        xlog("ruri_user_avp: '$avp(i:500)'\n");
        xlog("To URI after next_gw: $tu\n");
        xlog("Request URI: $rU\n");

  }
}
}




AND this is the error which i have got:

The best it will be to make a pull request via Github portal, it is
easier to review and see if there are conflicts on merging.

Here are few links for github docs on this matter:
  - https://help.github.com/articles/using-pull-requests/
  - https://help.github.com/articles/creating-a-pull-request/

Also, important to properly format the commit message:

There is parameter for lcr_id. you need to set max lcr_count in .cfg.

lcr_count
lcr_gw_count

I currently don't need such a feature.  It might be possible to
implement it by adding target_id field to struct target and to struct
matched_gw_info. Then add_gws_into_avps() function could include the id
in gw_uri_avps.  Feel free to do it.

It's a pity. May I ask (as feature request) to add it to the future

id of lcr_rule_target is not currently stored in gw_uri_avp.  only flags
and tag of selected gw is available.

[SR-Users] LCR

[Alexey V. Panfilov]

Hello,

I'm using LCR module in my kamailio setup. I can access to the
gw_uri_avp's value of matched gateway, but I'd like to get value of
selected id of lcr_rule_target. Is there any way to get it?

Thanks.

P.S. Access to value of custom table's field (for example, named as
'flags') of cr_rule_target will be better. I'd like to store at this
field the price of selected direction.

load_gws() tries to delete possibly existing avp values by this
statement:

delete_avp(gw_uri_avp_type|AVP_VAL_STR, gw_uri_avp);

obviously there is something wrong with if the avp needs to be deleted
by the script.

i'll try at some point try to figure out how to delete an avp based on
its name.

I added deletion of possible old ruri_user_avp value when next_gw() is
called first time after load_gws().

It is currently in master branch only, but I can commit also to 4.3
branch if this fixes the issue.

in load_gws function
  there is a delete_avp for gw_uri_avp as you mentioned . but in my
  view it needs a delete_avp for ruri_user_avp. 
  Because it is reloading gws for different route.

Hey;
Thanks for reply. before load_gws , setting ruri_user_avp to null solves
request uri problems.

Re: [SR-Users] LCR module : re load_gws uri errors

[ycaner]

Hello;
i found the problem i hope i can explain the problem to get solution.

when first usage of load_gws() and next_gw() functions , next_gw() fills all 
uri avps to ru_AVPs from gws tables. if it goes to failure route or route
again , it can re use ru_AVPs in next_gw(). so if recall the load_gws()
again for choose new route , it uses old uri avps in next_gw() function , it
is totally incorrect. if there is flag or parameter to define gws are
reloaded , it can null to ru_AVPs to correct gws informations.

i couldn't find why fromuri appending itself. searching about it.

Thanks.

does it work if you destroy (e.g. using avp_delete("$avp(x)/g"))
gw_uri_avp and ruri_user_avp before the second load_gws() call?

> i couldn't find why fromuri appending itself. searching about it.

if i remember correctly, lcr functions do not modify from uri.

[SR-Users] LCR module : re load_gws uri errors

[Yasin CANER]

  
  
Hello;
    After change $rU in  failure route , calling load_gws function.
so lcr module changes request uri and fromuser  and it is wrong.
here is example for more explain;
    
calls flows
1- 850xxx to 1021850yyy
2- 486 busy
3- going to t_on_failure route and then changing to request uri to
506aaa
4- re-format request uri to  20001506aaa
5- calling lcr load_gws(1,$rU);
6- lcr formatting to request uri to 20001506yyy
7- from user to (850xxx850xxx) appending last fromuser.

Re: [SR-Users] LCR Routing - Cost based routing

[DanB]

Hi Alexandru,

Well the concept is simple: on INVITE, you will issue a special format 
evapi request. You will receive the list of suppliers in the reply 
(which is received in a separate route) and you continue processing from 
there. These suppliers are simple tags so your creativity will be the 
limit of what you can do with them - eg: direct ip addresses received or 
tags of suppliers which you can further translate with drouting module 
or any alias related one.


For more information on LCR please find this year's presentation on 
Kamailio World (which I strongly recommend to be attended):


https://www.youtube.com/watch?v=Hsvcwleb-fY

You can also find the kamailio configuration which I have used in the 
worshop here:


https://github.com/cgrates/cgrates/tree/master/data/tutorials/kamevapi/kamailio/etc/kamailio

Let me know if further questions (or join our irc or mailing list so we 
do not create too much noise here).

[SR-Users] LCR Routing - Cost based routing

[Arun Kumar]

Hi

 is there any way to achive following usecase using carrier route / LCR
/ droude module

i have 10 different termination gateways, each gateways will have more than
1 destinations and each gateways will have different rate, for example

91 Destination ( there will be 1 entries like 91 )
gw1gw2   gw3   gw4gw5
0.001 0.007 0.003 0.002 0.003

now need to logic to load the these destination with cost and sort gateways
in order of longest match of dialled number,cost, priority for the dialled
destination, which will not use too much CPU and memory

Arun

Re: [SR-Users] LCR Routing - Cost based routing

[Alex Balashov]

‎Long story short: Kamailio supports primitive weight-based routing with its 
various internal modules, but not complex, jurisdiction and market-specific 
business logic which we commonly think of as LCR. 

For that, you need to somehow shoehorn your right selection algorithm into 
these modules' limited schema, write your own logic, or licence a commercial 
product which provides this, such as Sipwise's sip-provider (www.sipwise.com), 
or ours (www.csrpswitch.com), or various others.

Re: [SR-Users] LCR Routing - Cost based routing

[Alexandru Covalschi]

you already have cost, just write a script to transform it into weight, I
don't see a hard task here. It can be easily automated

2015-08-09 21:15 GMT+03:00 Arun Kumar mi2a...@gmail.com:

 hi Alexandru

so we have manually  set prefix , weight and priority
 depanding upon rates  ?  is there any avaliable way to automate or we have
 to rewrite/modify  the lcr/drouting module for rate selection  ,

 I know CGRateS allow cost-based LCR for Kamailio. Maybe there are some

 Hi

  is there any way to achive following usecase using carrier
 route / LCR / droude module

 i have 10 different termination gateways, each gateways will have
 more than 1 destinations and each gateways will have different rate,
 for example

 91 Destination ( there will be 1 entries like 91 )
 gw1gw2   gw3   gw4gw5
 0.001 0.007 0.003 0.002 0.003

 now need to logic to load the these destination with cost and sort
 gateways in order of longest match of dialled number,cost, priority for 
 the
 dialled destination, which will not use too much CPU and memory

It would.

Another idea:
You can also have only one lcr instance and keep gateways capabilities

a list generated by load_gws() skipping gateways which don't match your

Hello,

From what I understand about the LCR module is that the rules have
to be prioritized by the admin, be it manually or automatically by
an application.

Let’s say the LCR database has 10 gateways, each with their own
rules etc.

4 of these gateways support caller id spoofing and the others don’t.

But the other 6 are cheaper and Kamailio has to route a call using
a gateway which support caller id spoofing and is the cheapest of
the 4.

Would it be possible to tell the LCR module to select a gateway
based on certain capabilities and is the cheapest of the ones
which support a certain capability?

Re: [SR-Users] LCR with gateway capabilities

[Grant Bagdasarian]

The Tag column size is 64. If I make this larger in the database, will it be 
truncated once it is loaded into memory?
Through which list do I need to iterate? You mentioned the data is stored in a 
hash table, what is the name of this hash table?

Basically for each call I need to call the load_gws() function, which is O(N) * 
O(M).
What if I take a different approach and call a stored procedure (for each call) 
which does the selection of a gateway based on the supplied criteria.
Of course the tables would be optimized with indices for the best possible 
performance.

When comparing load_gws() (O(N) * O(M)) with the stored procedure approach, 
would there be a huge performance loss when taking the stored procedure 
approach?
I know this approach brings a whole new set of problem with availability and 
the loss of features, but for now I'm only interested in the performance aspect 
of both methods.

[Vitaliy Aleksandrov]

The Tag column size is 64. If I make this larger in the database, will 
it be truncated once it is loaded into memory?


According to modules source code Tag's max size is hardcoded and will be 
truncated. But this is not a bit problem. You can keep capabilities list 
in htable and only put a key for this htable info to the tag.


Through which list do I need to iterate? You mentioned the data is 
stored in a hash table, what is the name of this hash table?



load_gws() creates a list of gateways and next_gw() fetches them one by one.
After calling load_gws() you can just call next_gw() which puts gateways 
tag to the tag_avp. If current gateway doesn't have requested 
capabilities just call next_gw() again.


Basically for each call I need to call the load_gws() function, which 
is O(N) * O(M).


What if I take a different approach and call a stored procedure (for 
each call) which does the selection of a gateway based on the supplied

Who knows.. You can test it and share results with community :)


I know this approach brings a whole new set of problem with 
availability and the loss of features, but for now I’m only interested 
in the performance aspect of both methods.


Actually going this way you don't need LCR module at all. You can call 
stored procedure, lua/python/perl/... script, or request an external 
system using radius/xmlrpc. But be careful making blocking operations 
from a script or have enough number of kamailio processes.

[SR-Users] lcr module ping

[Debojit Kakoti]

Hi,
My current setup is
I have one kamailio server and one asterisk server.In the asterisk server I
have two trunk where there are two different PRI provider is used for
outbound call.
I am using uac_replace_from function to route call to different trunk of
the same server.

However I want to use lcr module and I can check if particular gateway is
up and down using lcr module and route the call.

But problem is In my current scenario the gateway is up but one PRI is down
for one provider and other one is up.So how to check if one sip trunk is
working and other one is not working? Can you suggest me a solution?

if i undertood correctly, i don't think you can use it since from the

for each prefix you can define gateways and give each a priority and

Re: [SR-Users] LCR

[Moritz Graf]

Hi Keith,

you can take the from userpart from the pseudovar $fU. Find further
infos on the pseudovar documentation site:
http://www.kamailio.org/wiki/cookbooks/4.1.x/pseudovariables

After that you can try to match that with the module regex, see
documentation here:
http://kamailio.org/docs/modules/4.1.x/modules/regex.html

But I recomend using app_perl. By that you get the whole SIP-message.
Apply PERL regexpower onto it and return some values via avps, or insert
branch directly in perl.

Depending on how sophisticated your LCR rules are using the LCR-Module
or any other module might also be worth a thought.

I have an issue where I have two carriers, one only accepts +44 then the

you can, for example, set a lcr_gw flag that tells what the

Juha,
Thank you for all of your help so far, but we are still totally stuck
trying to make this work.  We have double and triple checked our
configuration, database, and INVITE and everything is in-line with what
previously worked (in 1.5).  We are running 4.1.3, is that what you were
testing on?

What can I do to debug this?  I checked and we aren't seeing any of the
failed to compile regex errors in the logs.  We have 4 servers that are
all displaying the same behavior (read: ignoring the from_uri match on a
lower priority).

Any further help would be really appreciated.

you didn't answer if this issue is related to from uri pattern or
priorities in general.  if you remove from uri patterns, do priorities
then work?

if you can give me a simple example configuration where this problem
appears, i'll try it myself.

i made same kind of test that you have and routing worked as expected,
i.e., when request uri matched a common prefix, the one with lower
priority was tried first.

if you remove from uri constraint from the rule that had it, is lower
priority gw then selected first or doesn't priorities work at all for
you?

Right now, I would think that with our Priority of 0 on the route with the

Since we have the priority correctly set to evaluate in the order we want,

Re: [SR-Users] LCR

Hi,

I am having issues with trying to use multiple lcr_ids so I can route to
different groups. When I reload lcr it always only shows one group. I have
copied the first group exactly and just changed the number but can't work
out why it's not working.

Any ideas?
Thanks

If lcr is based on longest prefix, Pete could just use a little logic to 
implement longest match with alias_db_lookup (his original question). I store 
either a full number, a 10 number block or 100 block (by leaving off the last 
1 or 2 digits) and do the following:

$avp(callednumber)=$rU;
if(!alias_db_lookup(dbaliases))
{
strip_tail(1);
if(!alias_db_lookup(dbaliases))
{
strip_tail(1);
if(!alias_db_lookup(dbaliases))
{
$rU=$avp(callednumber);
}
}
}

If you give bigger numberblocks to endusers just add a level (of make a decent 
loop that checks the remaining length of $rU).

the param is there in order to save shared memory and speed up those

[SR-Users] LCR in Kamailio 4.0

[Geoffrey Mina]

Greetings,
I am migrating some 1.5 servers to 4.0 and I have some questions about how
the LCR module works now.

I am familiar with the concept of the gw table and the lcr table.  This was
pretty straight forward.  In the new version it looks like we have:

LCR Gateway List
LCR Rule List
LCR Target List

I read through the module documentation and it doesn't really speak to what
the new architecture is intended to accomplish.  Anyone have a quick
overview they would like to share which would help me understand the intent
of the data structure?

Thanks,
Geoff

Re: [SR-Users] LCR in Kamailio 4.0

[Gary Chen]

First thing to remember that lcr_id field is the one to link all three
tables together. Let's say that you want to create a lcr to route
international call starting with 011:
1) Create a row in lcr_gw table with id = 4, lcr_id = 3 and gateway IP etc.
2) Then create a row in lcr_rule table with id =2, lcr_id = 3 and prefix =
011
3) Then create a row in lcr_rule_target table to glue the gateway and
prefix together like this: lcr_id =3, gw_id=4 (Match the id value in lcr_gw
table), rule_id = 2 (Match the id in lcr_rule table)  also rest of the
fields like priority etc.

Hope this help.

[Geoffrey Mina]

What is the value of the target table?  Previously the lcr rule table was
directly tied to the gateway.  Is this simply to enable N:1 relationships
between lcr rules and gateways.

Also - any idea how to reload the LCR configuration without restarting
kamailio?  I previously issued kamctl fifo lcr_reload, but that doesn't
appear to work any longer.

Thanks!

Re: [SR-Users] LCR in Kamailio 4.0

[Gary Chen]

lcr_rule_target is like a glue to link lcr_gw and lcr_rule tables together
through rule_id and gw_id as well as lcr_id.
In this case if you have several sets of lcr_id, you will end up with
several duplicate gateway and rulls. It is not the best design and is hard
to use.

To reload lcr you do this: sercmd lcr.reload

 relationships between lcr rules and gateways.

 Also - any idea how to reload the LCR configuration without restarting
 kamailio?  I previously issued kamctl fifo lcr_reload, but that doesn't
 appear to work any longer.

 Thanks!

 First thing to remember that lcr_id field is the one to link all three

 international call starting with 011:
 1) Create a row in lcr_gw table with id = 4, lcr_id = 3 and gateway IP
 etc.
 2) Then create a row in lcr_rule table with id =2, lcr_id = 3 and prefix
 = 011
 3) Then create a row in lcr_rule_target table to glue the gateway and
 prefix together like this: lcr_id =3, gw_id=4 (Match the id value in lcr_gw
 table), rule_id = 2 (Match the id in lcr_rule table)  also rest of the
 fields like priority etc.

 Hope this help.

 I am migrating some 1.5 servers to 4.0 and I have some questions about
 how the LCR module works now.

 I am familiar with the concept of the gw table and the lcr table.  This
 was pretty straight forward.  In the new version it looks like we have:

 LCR Gateway List
 LCR Rule List
 LCR Target List

 I read through the module documentation and it doesn't really speak to
 what the new architecture is intended to accomplish.  Anyone have a quick
 overview they would like to share which would help me understand the intent
 of the data structure?

Re: [SR-Users] LCR in Kamailio 4.0

[Geoffrey Mina]

Thanks.  I included ctl.so module and now I can properly use kamcmd to
reload LCR.

 there as a new field to gw_uri_avp. then when next_gw() is called,
 rule_id stored with matched gw would need to be copied from the gw's
 matched_gw_info struct to a new rule_id_avp.
