Hi,

First of all say that I'm new to Kamailio. I've been working with asterisk for a while now and it's time to get started with the sip router project. My idea for a start is to reduce the load of our asterisk servers and once we have good knowledge on how kamailio works, migrate some of our services.

I've setup a server in our lab with kamailio 3.3.0 and siremis 3.3.0, created a user (subscriber) and registered with a softphone. So far OK.

Now I'm trying to make a call and route it through one of our asterisk servers for testing. To do this I need LCR module (thanks Sébastien, I wasn't subscribed to this list yet) and configure it.

After reading http://kamailio.org/docs/modules/stable/modules/lcr.html#id2553110 I've added in kamailio.cfg:

#!define WITH_LCR

#!ifdef WITH_LCR

loadmodule "lcr.so"
#!endif

#!ifdef WITH_LCR
# ----- lcr params -----
modparam("lcr", "db_url", DBURL)

modparam("lcr", "gw_uri_avp", "$avp(i:709)")
modparam("lcr", "ruri_user_avp", "$avp(i:500)")

modparam("lcr", "tag_avp", "$avp(lcr_tag)")
#!endif

And now I see LCR module being loaded at startup. But, I don't understand what gw_uri_avp, ruri_user_avp or tag_avp mean. Where can I find some doc/manual to understand what AVP means and does? (For example the $avp(i:709), etc.)

I've added a LCR GW, LCR TARGET and LCR RULE with the following data (I have no idea if it's completely wrong):

mysql> select * from lcr_gw;

+----+--------+---------+--------------+--------------------------+------+--------+------------+-----------+-------+--------+------+-------+---------+
| id | lcr_id | gw_name | ip_addr | hostname | port | params | uri_scheme | transport | strip | prefix | tag | flags | defunct |

+----+--------+---------+--------------+--------------------------+------+--------+------------+-----------+-------+--------+------+-------+---------+
| 1 | 0 | TEST | XX.XXX.XXX.X | test12345678.testing.com | 5060 | NULL | 1 | 1 | NULL | NULL | NULL | 0 | NULL |

+----+--------+---------+--------------+--------------------------+------+--------+------------+-----------+-------+--------+------+-------+---------+
1 row in set (0.00 sec)

mysql> select * from lcr_rule;
+----+--------+--------+----------+-------------+---------+---------+

| id | lcr_id | prefix | from_uri | request_uri | stopper | enabled |
+----+--------+--------+----------+-------------+---------+---------+

| 1 | 1 | .* | | | 0 | 1 |
+----+--------+--------+----------+-------------+---------+---------+

1 row in set (0.00 sec)

mysql> select * from lcr_rule_target;

+----+--------+---------+-------+----------+--------+
| id | lcr_id | rule_id | gw_id | priority | weight |
+----+--------+---------+-------+----------+--------+

| 1 | 1 | 1 | 1 | 1 | 1 |
+----+--------+---------+-------+----------+--------+
1 row in set (0.00 sec)

mysql>

Am I still missing basic stuff to be able to place a call ? (To get started I'd like to route all calls to our Asterisk server)

I'm glad to read documentation so If all of this is already somewhere please guide me cause I haven't found too much...

Thanks in advanced.

Regards,

Joel.
