Hello Samy,
this is driving me nuts.
take a look at that:
Kamailio 1
[root at kamailio-1 ~]# kamctl dispatcher show
dispatcher gateways
+----+-------+----------------------+-------+----------+-------+-------------------+
| id | setid | destination | flags | priority | attrs |
description |
+----+-------+----------------------+-------+----------+-------+-------------------+
| 1 | 1 | sip:10.2.45.98:5060 | 8 | 1 | | asterisk-1 |
| 2 | 1 | sip:10.2.45.103:5060 | 8 | 1 | | asterisk-2 |
+----+-------+----------------------+-------+----------+-------+-------------------+
[root at kamailio-1 ~]# kamctl dispatcher dump
SET_NO:: 1
SET:: 1
URI:: sip:10.2.45.103:5060 flags=IP priority=1 attrs=
URI:: sip:10.2.45.98:5060 flags=IP priority=1 attrs=
All is OK.
KAMAILIO 2
[root at kamailio-2 ~]# kamctl dispatcher show
dispatcher gateways
+----+-------+----------------------+-------+----------+-------+-------------------+
| id | setid | destination | flags | priority | attrs |
description |
+----+-------+----------------------+-------+----------+-------+-------------------+
| 1 | 1 | sip:10.2.45.98:5060 | 8 | 1 | | asterisk-1 |
| 2 | 1 | sip:10.2.45.103:5060 | 8 | 1 | | asterisk-2 |
+----+-------+----------------------+-------+----------+-------+-------------------+
as we can see setid = 1 for both servers, they actually read the data
from one and the same location which is a MySQL table.
[root at kamailio-2 ~]# kamctl dispatcher dump
SET_NO:: 2
SET:: 2
URI:: sip:10.2.45.103:5060 flags=IP priority=1 attrs=
SET:: 1
URI:: sip:10.2.45.98:5060 flags=IP priority=1 attrs=
Why the .... are they in different sets ?!?!?!?!
I really can't understand this one...
Anyone ... help ?
Thanks
