Hello David, haven't looked in detail on the specific errors that you observed. But if you are still in the implementation of this project, you might want to give the upcoming 5.3 version IMC module as try. It was extended considerably and also refactored/optimzed: https://www.kamailio.org/wiki/features/new-in-devel#imc If you need to stay on stable branch, I would suggest to debug this as well with some SIP traces (e.g. ngrep or wireshark). This way you could check if the MESSAGE is actually send out and a routing problem might be the cause. Cheers, Henning Cheers, Henning Am 27.08.19 um 17:58 schrieb david@aslo.us<mailto:david@aslo.us>: Hello everyone, I'm runing Kamailio 5.2.4 with enabled mysql, usrlocdb, presence, aliasdb, auth and NAT. I can register clients, establish calls and video calls, send IMs, etc. imc_rooms and imc_members tables were created when kamailio was installed. I've also checked imc-create.sql script and tables are correctly created. I'm trying to configure the IMC module, but my problem is that I'm not receiving system messages and messages sent to a room aren't correctly broadcasted to its members. I'm using following code provided by the IMC module documentation: modparam("imc", "rooms_table", "imc_rooms") modparam("imc", "members_table", "imc_members") modparam("imc", "hash_size", 8) modparam("imc", "imc_cmd_start_char", "#") ## route block ### if(is_method("MESSAGE") && (uri=~ "sip:chat-[0-9]+@") || (uri=~ "sip:chat-manager@")) { xlog("L_INFO", "going to imc: From [$fu] To [$tu] MSG [$rb]\n"); if(imc_manager()) #log("MESSAGE received -> processing with imc\n"); sl_send_reply("200", "ok -
