Re: [SR-Users] [sr-dev] new module: async - asynchronous SIP request processing in cfg

by Dan-Cristian Bogos

Hey Daniel, As said in the past, this module is good news, thanks for making it available. As a big fan of delayed billing, sleep() does a great job of delaying 200 OK from the upstream for me (useful for example with analogue/CDMA gateways sending 200 OK on ringback). Cheers, DanB

new module: async - asynchronous SIP request processing in cfg

by Daniel-Constantin Mierla

Hello, a new module is now in GIT master branch, named async. Its purpose is to provide asynchronous SIP request processing using t_suspend()/t_continue() mechanism from tm module. While the tm module had it for quite some time, it was not available for usage in configuration file. There are two functions implemented by now: - async_route(routename, interval) - execute asynchronously a route block after a time interval - aync_sleep(interval) - sleep asynchronously for a time interval and then resume SIP request processing See the readme for more details: http://kamailio.org/docs/modules/devel/modules/async.html Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com http://linkedin.com/in/miconda -- http://twitter.com/miconda

LCR module

by Fabian Borot

After installing the latest stable version 3.1.4 I noticed that I can not run any 'lcr' commands from the 'kamctl fifo' interface. I noticed that the lcr.so is not on the lib64/modules_k or lib64/modules_s folders so I guess is was not included at installation time: [root@registrar kamailio]# cd /usr/local/kamailio-3.1/lib64/kamailio/modules_k/ [root@registrar modules_k]# ls acc.so db_text.so drouting.so mi_datagram.so permissions.so rtimer.so statistics.so usrloc.so alias_db.so db_unixodbc.so exec.so mi_fifo.so pike.so rtpproxy.so textops.so xlog.so auth_db.so dialog.so group.so msilo.so pua_mi.so siptrace.so tmx.so auth_diameter.so dispatcher.so htable.so nathelper.so pv.so siputils.so uac_redirect.so benchmark.so diversion.so imc.so nat_traversal.so qos.so speeddial.so uac.so call_control.so domainpolicy.so kex.so path.so registrar.so sqlops.so uri_db.so cfgutils.so domain.so maxfwd.so pdt.so rr.so sst.so userblacklist.so [root@registrar modules_k]# cd /usr/local/kamailio-3.1/lib64/kamailio/modules_s/ [root@registrar modules_s]# ls acc_db.so avp.so diversion.so fifo.so nathelper.so pike.so speeddial.so uri_db.so acc_syslog.so db_ops.so domain.so gflags.so options.so print.so textops.so uri.so auth_db.so dialog.so eval.so maxfwd.so pdt.so registrar.so timer.so usrloc.so avp_db.so dispatcher.so exec.so msilo.so permissions.so rr.so uac.so xlog.so [root@registrar modules_s]# I checked the modules.lst file and it is not on the exclude list, because I did removed it along with db_mysql and db_odbc, so I expected it to be included but it is not. Am I missing something? This is from the syslog Jun 27 11:44:00 registrar /usr/local/kamailio-3.1/sbin/kamailio[3974]: ERROR: mi_fifo [fifo_fnc.c:470]: fifo command lcr is not available Jun 27 11:44:00 registrar /usr/local/kamailio-3.1/sbin/kamailio[3974]: DEBUG: mi_fifo [fifo_fnc.c:549]: entered consume Jun 27 11:44:00 registrar /usr/local/kamailio-3.1/sbin/kamailio[3974]: DEBUG: mi_fifo [fifo_fnc.c:549]: **** done consume and this is from the fifo interface: [root@registrar kamailio]# /usr/local/kamailio-3.1/sbin/kamctl fifo lcr reload 500 command 'lcr' not available [root@registrar kamailio]#

async processing in a module

by Matthew Williams

Hi, I'm working on a jsonrpc (client) module that we would like to make async, using t_suspend and t_continue from the tm module. I have a couple questions related to this. The way I understand these functions, t_suspend will freeze the transaction in shared memory and immediately return and t_continue will unfreeze the transaction. What I'm not clear on here is whether t_continue will continue processing of the transaction within the process that calls t_continue, or will it delegate to a worker process? I assume I should spawn an io process in child_init which will be responsible for sending/receiving on the socket(s), but what is the best way to communicate between processes? Is there a way to get a fd from fork_process (that can be written to by any child and read from using select() in the io thread)? This is my first attempt at a real module, so any pointers are greatly appreciated. Regards, Matthew WIlliams

by Daniel-Constantin Mierla

Hello, I just wanted to mark the 15000th development commit in our project (counted only on GIT master branch). It happened several days ago and it was done by the same person that did the first commit, Andrei: git log --pretty=format:"%h%x09%an%x09%ad%x09%s" --reverse | head -1 512dcd9 Andrei Pelinescu-Onciul Mon Sep 3 21:27:11 2001 +0000 Initial revision The 15000th one is: git log --pretty=format:"%h%x09%an%x09%ad%x09%s" --reverse | head -15000 | tail -1 8a90dd3 Andrei Pelinescu-Onciul Sat Jun 11 11:24:05 2011 +0200 core: remove unused variables + coding style I published the news about it on project sites as well: * http://asipto.com/u/37 * http://asipto.com/u/38 Now it's the time to look forward to the 20000th commit! Enjoy the summer, autumn comes with v3.2.0, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com http://linkedin.com/in/miconda -- http://twitter.com/miconda

an idea - the SIP browser - elsipo

by Daniel-Constantin Mierla

Hello, I want to present an idea and see if it is something people find benefits with such approach. Some time ago, due to existence of only SIP client applications (aka softphones) that have static GUI, which were designed for generic purposes, do not present what servces the currently used provider offers nor are easy to customize, I played with the idea of a SIP application with the GUI in HTML/CSS/Javascript. Being busy with Kamailio, the whole thing was postponed, but during last days I took the time and updated the code to latest developing tools (QT/Webkit and pjsip) and made it public on github, see: * http://asipto.com/u/3c A screenshot and some details in the wiki at: * http://asipto.com/u/3b The UI can be pulled from a remote site via http/https for example. The approach was to have a framework to render the UI, used QT/Webkit for that (cross platform, Linux, Mac OS X, Windows) and exported SIP API to Javascript. I worked with pjsip, but the system is plugin based, so pjsip plugin can be replaced, plugins for other things (not only sip/voip) can be written easily. The code is just for demo/prototyping, with the goal of showing feasibility. At this moment can be used to make/receive calls and send/receive instant messaging. In addition, content of UI can be carried by SIP messages - the examples added so far is to request some server statistics when clicking on a link of UI and the SIP server pushing periodically some info to a section of UI. Personally I don't have any plan to go into client side development, still the idea was too appealing to try and I thought would give lot of value and enable new features on SIP services to make user experience more pleasant. Therefore the target is to see if any of you think is something that worth pursuing and if yes, get people on board to develop it further from prototype phase. In the wiki I listed a part of my wish list with current VoIP/SIP services that would be trivial to implement with this approach. The naming as SIP browser instead of softphone hopefully suggest also the purpose of the application - to be able to browse the services offered by provider at that time and the provider to be able to push content back to application (on demand or periodically). Development was done on Mac OS X, a tarball with binaries for this OS is available for download on github - compiling for other OSes should go pretty straightforward. At the moment the idea poped up there was no such approach that I could find (at least not in open source space), did I miss something, are you aware of any similar approach? What is your opinion overall? Thanks, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com http://linkedin.com/in/miconda -- http://twitter.com/miconda
