Hi Daniel,
yes, there are still several issues we've found. I hope that you or the
other authors of the module will find some time to look into the issues.
1. last member in the chat room exits + call of ./kamctl fifo imc_list_rooms
crashes Kamailio.
Working example (no bugs): oz at abc.hr creates chat room chat-555 at abc.hr.
Doesn't write messages to the chat room. Exits (#exit). Receives message:
"The room has been destroyed". Call of ./kamctl fifo imc_list_rooms works
fine and doesn't display the room which was just destroyed.
Example which crashes Kamailio: oz at abc.hr creates chat room chat-555 at abc.hr.
Writes something to the chat room. Exits (#exit). No messages are displayed
in SIP client, although he should get "The room has been destroyed". Call of
./kamctl fifo imc_list_rooms doesn't display anything (although there are
other rooms besides chat-555 at abc.hr) and crashes Kamailio. In the database,
in imc_rooms, chat-555 at abc.hr is still there, but there are no members in
imc_members table. Log:

2. #remove command prints wrong info.
Example: oz at abc.hr creates chat room chat-555 at abc.hr. Invites
slavko at abc.hr(#invite
slavko at abc.hr). Invites pero at abc.hr. Both of them join with #accept.
oz at abc.hr removes pero (#remove pero at abc.hr). Pero's client displays
messages: "You have been removed from this room." and Pero can't send
messages to chat room any more. However, Oz's and Slavko's clients display
message: "<sip:pero at abc.hr> has joined the room".
3. #invite & #remove commands do not work after typing some text in
conference room.
Example 1: oz at abc.hr creates chat room chat-555 at abc.hr. Invites
slavko at abc.hr (#invite slavko at abc.hr). Invites pero at abc.hr. Both of them
join with #accept. Pero and Slavko write messages to chat room. Oz can
remove them at this point. However, after Oz writes a message to chat room,
he can't remove members any more and receives 500 command error. Log:

Example 2: oz at abc.hr creates chat room chat-666 at abc.hr. Invites
slavko at abc.hr. Slavko joins with #accept. Oz writes a message to chat room.
Invites pero at abc.hr. Imc manager returns 500 command error. (NOTE: If Oz
doesn't write any text to chat room, he can invite multiple users.) Here is
the log:

ROOM:: sip:chat-666 at abc.hr NR_OF_MEMBERS=2
MEMBER:: sip:oz at abc.hr
MEMBER:: sip:slavko at abc.hr
4. ./kamctl fifo imc_list_rooms command doesn't report correct number of
members in the room, number of members remains 0, although members have
successfully joined the chat room and ./kamctl fifo imc_list_members
sip:chat-555 at abc.hr returns correct number of members.

Ozren
