Unwanted INVITE while using TMCB_ACK_NEG_IN callback

by Ionut Razvan Ionita

Hi, My name is Ionut and I am a new developer in VoIP dev team in 1&1. Maybe you can help me with the following problem. I have the following scenario: UAC sends invite to UAS via Kamailio proxy, UAS responds with 491. I am trying to catch the ACK from the UAC in siptrace module using TMCB_ACK_NEG_IN. I successfully trace this message but there's one more unwanted call to this callback. It gets called for an INVITE request which I don't want to trace since the callback is called ACK_NEG_IN. From my understanding, this call is issued right after the ACK is sent to the UAS, which, for me, doesn't seem to be correct, since the callback should trace in ACKs not outs. TM code that's calling this callback is in t_reply.c:2291. Is this a bug? I can fix this issue easily in my code by checking whether or not the current message is an ACK in siptrace but it would be great if we would work for a fix to this issue. Regards, Ionut

When showing the INVITATION to the user, make sure to show the actual command prefix that has been configured via the module parameter. - URL: https://github.com/kamailio/kamailio/commit/4e2a3682569ebdfb33f09a3251382b2… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: make behavior of "#join" when room does not exist configurable Before, the command "#join" would automatically create the room and add the user to the room if it does not exist. That behavior can be confusing, especially on mobile where it is easy to miss-type room name. With the default behavior, the user would be added to the wrong room in that case. This patch introduces module parameter "create_on_join" which makes this behavior configurable. If set to 0, command join will not create the room if it does not exist and would send an error back to the user instead. - URL: https://github.com/kamailio/kamailio/commit/ab87f61a5889ad90229b0d3ec9dcae0… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: define message prefix with a macro This simple change makes it much easier to consistently change the prefix across all messages sent to the user. By default, the prefix is "*** ". - URL: https://github.com/kamailio/kamailio/commit/56c012664e9aadcb5f61f1093710d73… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: make behavior of "#create" configurable when room already exists The default behavior of the create command is to silently add the user to a group of one already exists. This can be confusing in some scenarios, e.g., when the user miss-types the room number. This patch adds a module parameter called "check_on_create" which makes it possible to customize this behavior. If set and the user attempts to create a room that already exists, the command will report an error. - URL: https://github.com/kamailio/kamailio/commit/dbdf69264d65a72490bea33b68b2d04… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: pass both parsed and unparsed URIs to all command handlers In order for the command handler to be able to send a response back when the corresponding room does not exist, e.g., when sending an error message, the handler must have access to the original unparsed URI. This change fixes one bug on the side: when sending a response, the response will be sent to the correct part number which was part of the original SIP URI. Previously, port numbers were ignored since the SIP URI to send the message to was constructed just from the username and domain parts. - URL: https://github.com/kamailio/kamailio/commit/b39822eff0c0857f9b5a5220504ad6d… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: consistent handling of command parameters. Most (all) commands takes parametes in one of the following forms: username, username@domain, sip:username@domain. The purpose of this change is to provide consistent handling of such parameters across all commands and their arguments. If a command takes a user or a room as a parameter, the user can provide just a username, username@domain, or a full URI sip:username@domain. The imc module will automatically obtain missing parts from other parts of the message, e.g., the Request-URI or From headers. In addition, all debugging and logging messages print the full URI of users and rooms. This significantly helps with debugging and development. - URL: https://github.com/kamailio/kamailio/commit/b00433b7710b7c4f879341258edad78… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: make #create command arguments optional With no arguments, the room name is taken from To header and the room will be made public. With one argument, if the value is 'private', a private room with name from To is created. If the value of the single argument is anything else, it is taken as room name and the room will be made public. With two argument, the first argument is room name and the second argument must be string 'private'. This change makes the #create command consistent with all other commands where the room/user name is also optional. - URL: https://github.com/kamailio/kamailio/commit/39457968f10be50b5ccf3f81c71dd68… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: rename command #list to #members. List was not very good name for the command, because the user would not know whether the command lists rooms or members within a room. The alias "list" is kept for backward compatibility. - URL: https://github.com/kamailio/kamailio/commit/e10974fd6d0ace3654e6b45eb6b5a9e… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: cleanup in invite related messages. In the original version, when the user receives an invitation to join the room, it was not obvious who is inviting. - URL: https://github.com/kamailio/kamailio/commit/d7e3d921a41de6ebc40ed13a788b9a0… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: consistent formatting of room/user names. No matter in which message a room URI or user URI is printed, always use the same function to consistent format the resulting string. In most cases, this means printing just the username portion of the full URI. - URL: https://github.com/kamailio/kamailio/commit/3de5f6da6a07c2d1afec7ddd3fdd6d1… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: improved #join command handling This patch improves the overall handling of the #join command on the chat server. If a user attempts to join a room they are already a member of, notify the user, instead of sending a broadcast that the user has joined again to the entire room. If a user attempts to join a private room, notify them that private rooms are by invitation only with a unicast message and send a broadcast to the entire room about the join attempt so that administrators can see the join attempt in order to decide whether or not to send an invitation to the user. - URL: https://github.com/kamailio/kamailio/commit/afe2a81a8e9ded484b4b161e3cd629e… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: notify user #leaving a room. When a user chooses to leave a room, send the broadcast first. That way, the broadcast will include the leaving user and they will be able to see that they have left the room successfully. Also, this behavior is consistent with the behavior of #join. - URL: https://github.com/kamailio/kamailio/commit/7ad7bb300e4ef2feb9691d7e6e0b2be… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: make message buffer larger Enlarge the buffer so that longer messages and user lists can be sent. A larger buffer is fine when TCP and or TLS is used. - URL: https://github.com/kamailio/kamailio/commit/ce45d49d837d5ba0f02ebba48899ef5… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: a small fix in #join When a user has left or been removed from a room and try to join again, make sure to test the IMC_MEMBER_DELETED flag, otherwise they'd be getting a message that they are already in the room. - URL: https://github.com/kamailio/kamailio/commit/d6760d680bed15d0f90c402ffca9b98… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: check arguments in #invite The command has one required argument: the name/URI of the user to be invited to the room. - URL: https://github.com/kamailio/kamailio/commit/ec243a6a205b647a83e3a3535fca362… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: implement command #add The command can be used by room owners and administrators to explicitly add other users as members to the room. It works a bit like the command #invite, except that the added user will have no chance to accept or reject the request. - URL: https://github.com/kamailio/kamailio/commit/e742fe4dc56e8ba37b4058996e037c8… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: implement command #rooms The command can be used to list all the rooms available on the chat server. - URL: https://github.com/kamailio/kamailio/commit/1073c6d0a133df342983829e430415a… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: add In-Reply-To header to MESSAGEs generated in response When generating a MESSAGE in response to a command, add a In-Reply-To header field to the second message with the Call-ID of the (original) message that carried the command. A chat client could then use the In-Reply-To header field to correlate requests and responses carried in-band in chat messages. - URL: https://github.com/kamailio/kamailio/commit/42a66e4f075c244e41e8b828f394e94… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: add Supported header to all chat room MESSAGEs. The header contains value "kamailio/imc" which indicates that the end-point is a chat room that supports the in-band signaling protocol implemented by Kamailio's imc module. - URL: https://github.com/kamailio/kamailio/commit/ba4de81405c7e1801ea7cafb5bbf5c8… Author: Jan Janak <janakj(a)cs.columbia.edu> Date: 2019-02-26T17:24:33+01:00 imc: report error if room owner sends #leave Previously, if the room owner send the #leave command, the room would have been automatically destroyed. That is somewhat dangerous and error prone, e.g., if the user sends the #leave command to the wrong room. With this patch, #leave reports an error if used by a room owner and the user is encouraged to use #destroy instead.
