HI,
I am facing a problem related to the IMC module.
I have installed kamailio 5.2.x and I tried to list the members of a
room-qsipchat.
In my test environment the kamailio.cfg file it is very basic, the
kamailio server listen on
tcp=192.168.100.192:15006
the client run on a PC with IP address 192.168.100.156
the imc outbound_proxy is set
modparam("imc", "db_url", DBURL)
modparam("imc", "imc_cmd_start_char", "#")
modparam("imc", "outbound_proxy",
"sip:sip-test.quintetto.it:15006;transport=tcp")
The client start by sending a #join message to kamailio and looking the
log file I can see that the room-qsipchat has been create, and also I
received the message 200 OK.
By using the tcpdump I can see the join message from the Client to
kamailio server and the reply from kamailio to the client.
When I send the #list message to the room-qsipchat , I expecting to
receive the message relate to room's members and the 200 OK message.
When I tcp dumping I saw the following messages
