Hi all, I started to implement fifo in my application to handle calls from know phones to unknown extensions and specific dial string/ extension. I use the api commands with esl (java client), outbound socket (with sendMsg). http://wiki.freeswitch.org/wiki/Mod_event_socket I looked at a lot of examples, for me I thought the right sequence to would be to add (register) user agents first (determined by myself) and later add caller in which all user agents would ring and the call would be handled after accepting the call from free user agent. My problem is now the right notation of the add fifo_member. I think I should use this for registering agents; http://wiki.freeswitch.org/wiki/Mod_fifo#Configure_for_Agent_Callback http://wiki.freeswitch.org/wiki/Mod_fifo#Simple%20On-hook%20Agent%20Login/Lo... http://wiki.freeswitch.org/wiki/Variable_fifo_member_wait sendmsg <uuid> call-command: execute execute-app-name: <one of the applications> execute-app-arg: <application data> sendMsg call-command: execute execute-app-name: set execute-app-arg: "fifo_member(add TestQue sofia/internal/1001%123.123.123.123)" I don't know if the () can be used in sendMsg, my queue name needs quotes "\'" and the callerid needs "@" or "%" with domain at end. When I execute the command I don't get errors, response is ok and in log of freeswitch I also see no errors (only set command). However when I execute fifo list or (verbose_list) from FS CLI, I don't see any user agents registered. If I put the caller in my queue, I see only the caller registered (callers) http://wiki.freeswitch.org/wiki/Mod_fifo#Terminology http://wiki.freeswitch.org/wiki/Mod_fifo#list.7Clist_verbose Below works, only my created queue is missing lag, call timeout and simcount! Put a caller into a FIFO queue sendMsg call-command: execute execute-app-name: fifo execute-app-arg: TestQue in somesoundfile.wav someothersoundfilemusic.wav Kind regards, Peter Ps, I hope somebody can advise !!!!
