thanks Daniel,

Sorry I make mistake, I was calling the same UAC which called, even if I 
am a newbie, this error is very ridiculous
I restest, 900123 call 00900223, the result is in attached file "ngrep 
not working"
And yes, 900223 and 00900223 are the same SIP account, I add 00 before 
the destination when I dial  because with only 900223, I couldn't debit 
balance when I installed callcontrol and cdrtool, to make it works I 
insert in dbaliases table of kamailio database the following lines:
mysql> use kamailio_db
Database changed
mysql> select * from dbaliases;
+----+----------------+--------------+----------+------------------+
| id | alias_username | alias_domain | username | domain           |
+----+----------------+--------------+----------+------------------+
|  1 | 00900223         |              | 900223   | sip.malagasy.com |
|  2 | 00900123         |              | 900123   | sip.malagasy.com |
+----+----------------+--------------+----------+------------------+
2 rows in set (0.00 sec)
and just with kamailio+cdrtool+callconrol enabled and with this 
configuration in mysql table, I can debit balance for SIP account which 
is prepaid but maybe it's not the right method too, I'll re-check the 
documentation of cdrtool/callcontrol


So,  I change the values of alias user_name column to be like in 
username column, I enable in kamailio conf all the WITH_NAT directive so 
I enable the use of rtpproxy too, I restart kamailio, make a test call 
and still not working, from ngrep (in attached file) I see not enough 
credit but in my tables of cdrtool's database I still have this:
mysql> select * from prepaid;
+----+-------------+-------------------------+-----------+---------------------+-----------------+-----------------+--------------+
| id | reseller_id | account                 | balance   | 
change_date         | active_sessions | session_counter | max_sessions |

mysql> select * from billing_rates;

+----+-------------+------+-------------+-------------+-------------+--------------+---------------+----------------+
|  1 |           0 | 4G   | 900         | audio       | 0           | 1 
          |               |                |
+----+-------------+------+-------------+-------------+-------------+--------------+---------------+----------------+

Last, I re-do an update at table dbaliases and for alias_username column 
I re-put 00, in kamailio configuration file I commented out the 
following lines:
[...]
##!define WITH_NAT
[...]
         remove_hf("Route");
         if (is_method("INVITE|SUBSCRIBE"))
         {
                 [...]
                 #rtpproxy_offer();
                 [...]
         }
[...]
route[RELAY] {
if (is_method("INVITE|SUBSCRIBE")) {
     #rtpproxy_offer();
     #t_on_reply("1");
     [...]
}
#onreply_route[1] {
#      if (status=~"[12][0-9][0-9]")
#               #force_rtp_proxy();
#               rtpproxy_offer();
#}

I don't kill rtpproxy process, I restart kamailio, make a test call, and 
it works again, so I don't know what to do to have rtpproxy works

Regards.
