I have installed openser-1.3.2-nontls on 192.168.0.3. The phones are 0103(a)192.168.0.3, 0203(a)192.168.0.3 and 0303(a)192.168.0.3. To test multidomain support, I added modparam("auth_db|auth_diameter|group|uri_db|usrloc","use_domain",1) and changed from "uri==myself" to "is_uri_host_local" in openser.cfg. I added two phones 9101 and 9102 with domain 192.168.0.32. These two phones are registered on mysql db as follows; # openserctl add 9101(a)192.168.0.32 password 9101@localhost # openserctl add 9102(a)192.168.0.32 password 9102@localhost I also set up 192.168.0.32 for eth0:0. eth0 is 192.168.0.3. Then, I check: [root@p4c8 multidomain]# openserctl domain show database engine 'MYSQL' loaded Control engine 'FIFO' loaded entering fifo_cmd domain_dump 192.168.0.3 192.168.0.32 FIFO command was: :domain_dump:openser_receiver_6329 [root@p4c8 multidomain]# openserctl domain showdb database engine 'MYSQL' loaded Control engine 'FIFO' loaded +----+--------------+---------------------+---------+ | id | domain | last_modified | version | +----+--------------+---------------------+---------+ | 2 | 192.168.0.3 | 2008-04-09 16:13:12 | 0 | | 4 | 192.168.0.32 | 2008-01-01 00:00:00 | NULL | +----+--------------+---------------------+---------+ [root@p4c8 multidomain]# openserctl ul show database engine 'MYSQL' loaded Control engine 'FIFO' loaded entering fifo_cmd ul_dump Domain:: aliases table=512 records=0 max_slot=0 Domain:: location table=512 records=3 max_slot=1 AOR:: 0203(a)192.168.0.3 Contact:: sip:0203@192.168.0.102 Q= Expires:: 295 Callid:: 91741a3a146e34bb(a)192.168.0.102 Cseq:: 101 User-agent:: Grandstream BT110 1.0.8.23 State:: CS_SYNC Flags:: 0 Cflag:: 0 Socket:: udp:192.168.0.3:5060 Methods:: 5695 AOR:: 0303(a)192.168.0.3 Contact:: sip:0303@192.168.0.103 Q= Expires:: 294 Callid:: 4c0a9450bb744c33(a)192.168.0.103 Cseq:: 101 User-agent:: Grandstream BT100 1.0.6.8 State:: CS_SYNC Flags:: 0 Cflag:: 0 Socket:: udp:192.168.0.3:5060 Methods:: 5695 AOR:: 0103(a)192.168.0.3 Contact:: sip:0103@192.168.0.101 Q= Expires:: 295 Callid:: 60507d20c32ac791(a)192.168.0.101 Cseq:: 101 User-agent:: Grandstream BT110 1.0.8.23 State:: CS_SYNC Flags:: 0 Cflag:: 0 Socket:: udp:192.168.0.3:5060 Methods:: 5695 FIFO command was: :ul_dump:openser_receiver_6424 openserctl ul show does not show 9101(a)192.168.0.32 and 9102(a)192.168.0.32 !?
