[Serusers] Questions re. MySQL
by frq ser 11 Apr '08

11 Apr '08

Hi, Here's a set of basic questions for which I need your help. I want to play different announcements based on the caller's history. For simplicity, I want ann1_user1.wav to be played for the first call, and ann2_user1.wav for all subsequent calls from the 1st user. Similarly for 2nd user, the files would be ann*_user2.wav. 1) I want to have a basic record of the number of times a user has called the SER(ie, sent an INVITE). Which table and column in mySQL can I use for this purpose. Also, how can I write the integer using SER commands (ie something that I can put in ser.cfg file). There is an example ( http://www.iptel.org/write_custom_text_to_mysql_acc_table) which uses 'acc_db_request', but it can only write to sip_status column in acc table. How can I modify /write to to any general field in mysql? 2) Subsequently, how can I retreive this value from mysql through some command in ser.cfg file. I want to use this value in an 'if' statement and redirect the process flow accordingly. 3) I was thinking of rewriting the uri to make it 'ann1_user1@xxxxx' and sending the request to early_announce application so that the user hears different announcement based on username and their call history (ie whether this user has called before or not). However, I am not very clear about how to do this. Is there any simpler method to do this. The final aim of this whole exercise is to demonstrate call differentiation based on username and user history. So if someone has a better idea then please do share it. Thanks for the help and accept my apologies for squeezing so many questions into a single message. Regards, Frq

[OpenSER-Users] My application destroys registration
by kriko 11 Apr '08

11 Apr '08

Hi! I have a problem with wesip, it works but it destroys client registration. I added simple if statement, which executes app on wesip server (only on INVITE): #app server conn if(!as_relay_t("examplesvr")){ t_reply("500","No App Server"); } If you look at wesip log: http://files.myopera.com/kriko/code/seas_log.txt You can see that wesip doesn't process this request, since the app only responds to INVITE, looking closer at this line: --- SIP/2.0 481 Call Leg/Transaction Does Not Exist --- If you would like to look at app it is here (really simple thing): http://files.myopera.com/kriko/code/sample.java What am I doing wrong? Is it because I'm using t_reply in wrong place or there is something else. I don't think it is my app, since it is not being executed. -- (\__/) (='.'=) (")_(")

[Serusers] Problem related to exec_msg
by frq ser 11 Apr '08

11 Apr '08

Hi, I am trying to understand the 'exec_msg' command as described in Section 4 of SER Admin Guide. I am just trying to echo the user name (1001) of the caller on the screen. I use the config file given at the end. On receiving the INVITE message, SER DOES echo the user name, but I also get some warning and error messages as shown below: #> /opt/ser-sems/sbin/ser -f /xxx.../voip/ser_expt.cfg Listening on udp: 192.168.3.208 [192.168.3.208]:5070 tcp: 192.168.3.208 [192.168.3.208]:5070 Aliases: tcp: xxx:5070 udp: xxx:5070 WARNING: no fork mode stateless - initializing 0(0) Maxfwd module- initializing textops - initializing exec - initializing 0(0) INFO: udp_init: SO_RCVBUF is initially 107520 0(0) INFO: udp_init: SO_RCVBUF is finally 262142 2(0) INFO: fifo process starting: 2803 2(0) SER: open_uac_fifo: fifo server up at /tmp/ser_fifo... 2(0) WARNING: no fifo_db_url given - fifo DB commands disabled! 0(2801) Main Route... 0(2801) Inside search from-1001... 1001 0(2801) child process 2805 exited normally, status=0 0(2801) INFO: dont_fork turned on, living on 0(2801) WARNING: SIGPIPE received and ignored 0(2801) ERROR: exec_msg: cmd echo '1001' failed. exit_status=-1, errno=10: No child processes 0(2801) WARNING: receive_msg: error while trying script Can someone tell me how I can get rid of these messages. My aim was just to get the user name displayed, and this has been achieved. I just want to understand the reason for these warnings and error messages.

[OpenSER-Users] Recommendations for IM/Voice/Video client
by Adrian Georgescu 11 Apr '08

11 Apr '08

For those interested, you can monitor the progress of development for the multi party chat functionality based on MSRP here: http://www.msrprelay.org/ http://www.msrprelay.org/wiki/MSRPChatSoftwareDesign Adrian >>>>>>>>>>>> I've tryed Bria but in its web page it appears: IM Management - Send instant messages to groups - Use IM tabs for multiple IM conversations in one window - See IM alerts for incoming IM It's not as a IM conferencing in a server side, but maybe enought... Anyway, you can do a conference with IMC module and create contacts like "IM room 1", "IM room 2" in each client. Of course, for now there is no way to know which users are joining a conference. There are two RFC's about it: - SIP Event Package for Conference State http://tools.ietf.org/html/rfc4575 - SIP Call Control - Conferencing for User Agents http://tools.ietf.org/html/rfc4579 but AFAIK there are not yet client side implementation. -- Iñaki Baz Castillo

[OpenSER-Users] Recommendations for IM/Voice/Video client
by Robert McGilvray 10 Apr '08

10 Apr '08

This is a little off-topic, but figured it was a good place to ask. We're interested in deploying OpenSER coupled with a SIP client primarily used for IM, but also for voice and video conferencing. I'm looking for feedback and recommendations on clients from people that may do this already or have been involved with it. So far one of the better ones looks like Bria (a step up from Eyebeam) from CounterPath. One short coming though is the lack of IM conferencing. I could probably rig something up with IMC but our users would prefer to have a clicky GUI for it. This is for an enterprise and it'd be nice to be able to brand it. Thanks -Bob

[OpenSER-Users] forwarding responses to early in TM
by Taisto Qvist 10 Apr '08

10 Apr '08

Hi folks, When I am doing forking I am getting a puzzling result concerning forwarding of responses, and I'm wondering how script needs tweaking. When recieving a 6xx on one branch, the TM-module automatically generates CANCEL to cancel the remaining branches(I wouldnt mind if this was configurable), but the puzzling thing is that it forwards the 603 _before_ it has terminated the remaining client transactions. (It sends cancel but it doesnt wait for final responses of the invites its cancelling, just forwards 6xx directly.) A similar scenario happends when I let Timer C pop. My TM-module will send a final response on the server-side at the same time as it starts to cancel the client side. But since one of the client txns just might result in a 2xx(INV) I cant forward the final response until ALL client txns are done, if I am going to follow the rfc properly. I thought the TM module would keep track of all client txns for "me", but it seems it isnt, so is this something I should "manually" handle in my script? Regards Taisto Qvist
