[OpenSIPS-Users] use of is_from_gw directive from drouting module.

[Miguel J. López Valverde]

Dear Bogdan-Andrei

I've tried to asign a new group for this providers, (group 3, I can't
asign it to group 0 because this group is used by another type of
users). I've filled dr_groups registers with this new information,
(dr_gateways was filled before, on 1.8 release):

select * from dr_gateways;
+----+---------------------+------+----------------+-------+------------+-------+------------+-------------------+
| id | gwid                | type | address        | strip | pri_prefix
| attrs | probe_mode | description       |
+----+---------------------+------+----------------+-------+------------+-------+------------+-------------------+
|  1 | Provider_0          |    2 | XXX.XXX.XXX.XXX|     0 | NULL
| NULL  |          0 | Provider0_incoming|



select * from dr_groups;
+----+-------------------+-----------------+---------+---------------------------+
| id | username          | domain          | groupid | description
|
+----+-------------------+-----------------+---------+---------------------------+
| 24 | Provider_0        |  XXX.XXX.XXX.XXX|       3 |
Provider0_incoming        |


And the new configuration:

        } else if (is_from_gw()) {
                # request comes from gw
                setflag(21);

        } else if (is_from_gw("3","n")) {
                # request comes from gw with strange udp-ports
                setflag(21);
        }

With this configuration, the is_from_gw() directive is working right for
providers without dr_groups db information and using 5060 port, but the
is_from_gw("3","n") aren't working, it don't match with providers of
group 3 and working with ports diferents of 5060.

¿Are this configuration wrong?.

Thankyou very much for your help.

Hello Miguel,

Starting with 1.9, DR module does SIP wise resolving of the destination
(in order to find all the IPs behind the a FQDN, via NATPR, SRV and A
lookups). A side effect is that according to SIP, no port means 5060.

In your case, the "n" flag should do the trick - but I understand that
when using it, your problem is what group to use (by the way, "" group
is translated to group 0 ) . Are your GWs in various groups?
