more on asynchronous processing in config
by Daniel-Constantin Mierla 05 Jul '11

05 Jul '11

Hello, over the weekend I exported to config file the two main functions from tm that allow to suspend the execution of a SIP request and resume it in another place. They are exported through tmx module: - t_suspend() - will suspend the execution of current sip request and then you can do something else (like processing the next request) - t_continue(tindex, tlabel, rtname) - continue the processing of SIP request suspended in the transaction identified by tupple (tindex,tlable) with the actions in route[rtname] After t_suspend() you can get the transaction identifier (tindex, tlable) via pseudo-variables $T(id_index) and $T(id_label), e.g.: if(t_suspend()) { xlog("sip request suspended in transaction [$T(id_index)/$T(id_label)]\n"); exit; } One example of usage can be passing the $T(id_index) and $T(id_label) via mqueue to another process for further handling. So, besides the new additions, now following cfg tools can be used to do asynchronous operations directly via config: - the mqueue + rtimer module - pass a task via mqueue and get it in rtimer specific processes to run it further - async module - intended to collect asynchronous specific implementation, for now able to sleep and execute a specific route after a time interval Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com http://linkedin.com/in/miconda -- http://twitter.com/miconda

"select count(*)" with avp_db_query always returns null
by Andrade Ricardo (CI/AFU1) 05 Jul '11

05 Jul '11

Hi list, Perhaps this fits better into a bug report, but I'd like to know if somebody out there experienced a similar issue. I am executing a "select count" query using the avp_db_query function, but it is not storing the results in any avp. Other queries are working fine. I use db_mysql connected with a mysql 5.1 server. I have tested this with kamailio-3.1.0 and kamailio-3.1.3, both didn't work. In an old box (version 1.3.x), the same query was returning the correct value. --------------------------------------------------- Here is the case which is not working: Code: avp_delete("$avp(s:count)"); $var(ret) = avp_db_query("SELECT count(*) FROM subscriber where username='foo'", "$avp(s:count)"); xlog("L_INFO", "var(ret)=$var(ret) avp(s:count)=$avp(s:count)"); Output: INFO: <script>: var(ret)=1 avp(s:count)=<null> (notice the return code 1, which means that the query was successfull and there should be some output value stored in the avp, but it is <null>) --------------------------------------------------- And here is one case which works as expected: $var(ret) = avp_db_query("SELECT id FROM subscriber where username='foo'", "$avp(s:count)"); Output: INFO: <script>: var(ret)=1 avp(s:count)=11 --------------------------------------------------- Thanks in advance for any feedback. Best regards, Ricardo Andrade.

Kamailio 64bit Compile Errors
by Nathaniel L Keeling 05 Jul '11

05 Jul '11

I am trying to install Kamailio 3.1.0 on Solaris 10 that is a sparc machine (v120) and is running a 64bit OS. When I originally performed the compile utilizing the instructions from the website, I was getting warnings about using 32 bit headers. I was able to compile and install successfully, but when I started Kamailio, loading of modules were failing due to "not found" error. The warning messages: "atomic/atomic_sparc.h:41:2: warning: #warning "sparc32 atomic operations support not tested"" I thought was because the target architecture specified sparc and not sparc64, so I tried specified the target architecture as listed below which got rid of the warning messages but then I got ELFCLASS32 error messages. What is the proper way to create a 64bit version of Kamailio on a sparc Solaris 10. It seems like the target architecure is not being configured properly and that may be causing other problems. I have included output from different commands about the environment and the commands that I entered to compile Kamailio. # make FLAVOUR=kamailio cfg target architecture <sparc>, host architecture <sparc64> # isainfo -n sparcv9 # uname -p sparc # uname -m sun4u # isainfo -v 64-bit sparcv9 applications vis 32-bit sparc applications vis v8plus div32 mul32 # isainfo -b 64 Here is what I entered to try and force the building of a 64 bit version and a sample error that I was getting. make FLAVOUR=kamailio prefix=/usr/local/kamailio-3.1 CPU=ultrasparc ARCH=sparc64 cfg LD (gcc) [M lcr.so] lcr.so ld: fatal: file /usr/local/lib/libpcre.so: wrong ELF class: ELFCLASS32 ld: fatal: File processing errors.

Presence and Presence_mwi
by Marvin59 05 Jul '11

05 Jul '11

Hi all, I am trying to configure kamailio-3.1.4 in order to send me MWI Notify when there is change in messages. I have already configure it, in order to use a FreeRadius to authenticate my users but I have no idea to use Presence and Presence_mwi module. I need this behavior : - The phone send me a subscribe, then if it authorize i send it the Notify with the messages-waiting. - I must write myself the notify request because an external script will tell me if there are messages waiting. I have looked here (http://www.kamailio.org/docs/modules/3.1.x/modules_k/presence.html#id2614273 and http://www.kamailio.org/docs/modules/3.1.x/modules_k/presence_mwi.html). If someone has further informations .... Thanks for your help.

Session authorization just before initiate it
by Roberto Fichera 05 Jul '11

05 Jul '11

Hi All in the list, I'm new to Kamailio but I'm actually able to quickly setup a server, including also the SIP presence, looking at the example I found at http://kb.asipto.com/kamailio:presence:k31-made-simple which explain very well how to do it. I also made some changes in the final setup and everything seems working well, I can have audio/video/chat session including the presence status of any user. Now I would like to improve my testing setup so that for each call request Kamailio receive, I would like to perform some SQL lookup for deciding if the conversation might be established or not. About the SQL lookup I read about the SQLOPS module, it seems really easy to use, but I don't know where to put such check before the INVITE. Could someone give me some hints? P.S: Indeed, I need to read some good documentation about how to code a Kamailio config file. Any URL to suggest? Thanks in advance, Roberto Fichera.
