Re: [SR-Users] FW: (Devel) Segmentation fault using pua_dialoginfo
by Daniel-Constantin Mierla 15 May '12

Hello, interesting that the output of bt shows inline core_hash function prototype with same parameters as publ_cback_func, not being able to spot eventual wrong parameter values. Anyhow, in the gdb, can you do the commands: frame 1 p *hentity and send the output? Let's see the value of the pub uri for which hashing function crashes. What are the parameters for pua and pua_dialog info you set in the config file?

kamdbctl create changing mysql root password
by Tim King 15 May '12

15 May '12

This is not the first time I have had this issue during installation, but this time around I am having difficulty figuring out what I am doing wrong. Mysql is up and working, and client works. I can connect to it with the client and run queries without issue. When I run kamdbctl create I get the following. INFO: test server charset INFO: creating database openser ... ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) ERROR: Creating core tables failed! It creates the database but than fails to create tables. From this point I can no longer connect to mysql with what was my root password. I have to go through the process of resetting my root password before I can log back into mysql. How is this script chaning or corrupting my mysql root password? This is the relevant content of my kamctlrc file: # $Id$ # # The Kamailio configuration file for the control tools. # # Here you can set variables used in the kamctl and kamdbctl setup # scripts. Per default all variables here are commented out, the control tools # will use their internal default values. ## your SIP domain SIP_DOMAIN=sbc.mydomain.net ## chrooted directory # $CHROOT_DIR="/path/to/ chrooted/directory" ## database type: MYSQL, PGSQL, ORACLE, DB_BERKELEY, DBTEXT, or SQLITE # by default none is loaded # # If you want to setup a database with kamdbctl, you must at least specify # this parameter.

Kamailio CS_Dirty
by Albert Petit 15 May '12

15 May '12

Hello, On a Kamailio deployment it seems some users get to a wrong state and permanently keeping in: CS_DIRTY Expires==0 for some long times (even half an hour). When they're in this status seems system cannot reach them. Normally , when working on USRLoc mode 2 if the registration expires usually what I observed is that it just not appears on 'kamctl ul show' The affected users are seen like this: AOR:: blue4 Contact:: sip:Blue4@192.168.101.6:5700 Q= Expires:: deleted Callid:: efc560dc2dbd248d4d1f9d39633773df Cseq:: 49995 User-agent:: PoC-client/OMA1.0 Genaker_X-Platform_IMS_SDK/v2.0 State:: CS_DIRTY Flags:: 0 Cflag:: 0 Socket:: udp:10.133.21.141:6666 Methods:: 8143 The refresh from the clients seem to come intime however some users (and not all) got to this CS_DIRTY state instead of being removed or refreshed. The client refresh looks to arrive in-time so it should be refreshed. Which could be a common cause (misconfiguration?) for this type of problem? If not, could enable debug mode for usrloc or I need to enable for full kamailio? Thanks Albert

Question about dialog module (state 1)
by Ricardo Martinez 15 May '12

15 May '12

Hello. I’m using the dialog module to keep control of simultaneous calls. In some cases, and I’m still trying to find why this happens, the dialog stays in “STATE:: 1”, which according to the docs is a dialog which no provisional response has been sent yet. Is there a way to eliminate this kind of dialogs??? When I list the dialogs I can see : dialog:: hash=2523:2040584107 state:: 1 ref_count:: 1 timestart:: 0 timeout:: 0 callid:: 25b8e5354ca0850a4d0bd9c43eeb617a(a)pxext.redvoiss.net from_uri:: sip:557100052213@pxext.redvoiss.net from_tag:: as10dc7c85 caller_contact:: sip:557100052213@200.68.19.44:5060 caller_cseq:: 103 caller_route_set:: caller_bind_addr:: udp:64.76.154.110:5060 callee_bind_addr:: to_uri:: sip:0981985480@pxext.redvoiss.net to_tag:: callee_contact:: callee_cseq:: callee_route_set:: when I try to eliminate this dialog : kamctl fifo dlg_terminate_dlg 25b8e5354ca0850a4d0bd9c43eeb617a(a)pxext.redvoiss.net 500 command 'dlg_terminate_dlg' failed Thanks in advance, Regards, Ricardo Martinez.-

[SIREMIS] send MI Commands to multiple kamailio servers
by SamyGo 15 May '12

15 May '12

Hello all, Following through the manual at : http://kb.asipto.com/siremis:install32x:mi-commands I'm able to send MI commands on external/remote server But next hurdle is how can I define multiple remote servers i.e <Remote name="remote0" address="127.0.0.1" port="8033"/> <Remote name="remote1" address="192.168.2.156" port="8033"/> <Remote name="remote2" address=" 192.168.2.150" port="8033"/> Is there any already working configuration else I think I may need to start a surgery on siremisMICommands.php file and make it loop over the remote tag and disptach commands until loop ends. is there any "MI-proxy" sort of thing available !!? Regards, Sammy.

Pickup group implementation in Kamailio
by M.C. 15 May '12

15 May '12

Hi all, I want to implement a "group pickup" (asterisk like) with Kamailio and Snom phones. I found in the changelog this comment: "- an useful application - call pickup: - INVITE comes in, callee is in a pickup group - store callid, cseq, etc in database or notify the other phones in the group (easy to do for snom phones and extra programmable buttons) via uac_req_send() - send a remote control command telling which call to pickup (callid, cseq) and where to redirect. In config, call t_cancel_callid(). in failure route for INVITE catch the cancelled transaction (flag is set), get the new destination (e.g., stored in htable) and forward the invite there"" regarding new functions in tmx module, but I have found no examples in kamailio documentation. Is this the way to implement a group pickup in kamailio? Regards, Matteo

modify connection information field from a 200 OK response
by Openser Kamailio 15 May '12

15 May '12

hi, I try to change the IP address in connection information field from a 200 OK request passing through Kamailio. I want the IP address of the Kamailio in connection information. So, I've tried rtpproxy_answer("","@IP kamailio"), rtppproxy_offer("","@IP kamailio), rtpproxy_manage("","@IP kamailio"). It didn't change anything. Thanks for Help!
