Adding FS version and machine-readable uptime to heartbeat events
by Daniel Swarbrick 13 Jul '12

13 Jul '12

Does anybody have any objections if I add the FS version string and a machine-readable uptime to heartbeat events? Having the version string available in the heartbeat just seems like a good idea considering that we have other elements such as the core UUID and hostname in the event. And having the uptime as a machine-readable int will make it easier for monitoring apps to detect if the switch has rebooted (uptime goes backwards), assuming they missed other events that may have indicated that. I suggest using event header name "FreeSWITCH-Version" for the version. I see that FS tracks uptime down to millisecond resolution. Is it really this accurate? If so, then how about "Uptime-usec" ?

Conference recording pause/resume problem
by Mariusz Czulada 13 Jul '12

13 Jul '12

Hi, I try to prepare a patch which allows to pause/resume a given recording. I'm in the middle of the road: pause is working, by resume - not :(. I'd like to ask for your help in finding a problem. I'm not sure if I handle member and file flags in the thread sub correctly. BTW. I lost some time playing with member-fnode until found fh in conference_record_thread_run is a proper handler. What is the conference_file_node_t member->fnode used for, if not for handling a recording file? Regards, Mariusz

Conference outcall_flags Not Working As Expected
by Anthony Novatsis 11 Jul '12

11 Jul '12

Dear All, Using conference outcall, I have several outcalls with different member flags (using the recently added outcall_flags variable). In one conference_set_auto_outcall, I have the following data string: {outcall_flags=moderator|endconf}user/1000@$${domain},user/2000@ $${domain}|user/3000@$${domain} The users 1000 and 2000 are called simultaneously first and if they fail to answer or reject, user 3000 is called. All is working correctly from the call setup perspective. However the member flags are not always correct. They are only correct if user 1000 answers the call. It seems that they are only applying to the first user but I was expecting that they would apply to all users. Firstly, is the observed behaviour correct? And if yes, does anybody know how I can achieve the desired result? Any help would be much appreciated. Thank you in advance. Best regards, Anthony

Compilation Errors
by Ian Bonham 11 Jul '12

11 Jul '12

Hi, I hope I'm posting to the right list, I'm new to these parts! I have been running a test of FreeSwitch on Ubuntu 12.04, retrieved using Git, and it compiled and installed fine, and I've enjoyed learning about it. I needed to switch on avmd, so set the flag in modules.conf and went to recompile. Now, whenever I try to compile, I get the failure copied onto the end of this email. I've pulled down a fresh copy and still it won't play ball. Is something in avmd stopping mod_sofia compiling? If anyone can throw any light on this I would really appreciate it, as I'm using Freeswitch in a predictive dialler I'm building so need some form of voicemail detection.

Can someone explain this block of code to me re: OPTIONS pings and timing
by Darren Schreiber 11 Jul '12

11 Jul '12

Hi all, We are seeing a situation on all of our FreeSWITCH instances where OPTIONS pings are happening at an interval of about 45 seconds. I was expecting these to fire roughly every 30. I looked at sofia_reg.c to see when sofia_reg_nat_callback() gets kicked off and it's fired from within the sofia_reg_check_expire, which is fired from within the sofia_profile_worker_thread_run() thread. If I'm understanding the loop inside the sofia profile worker thread correctly, it pops requests off the SQL stack to process them in batch, then runs the sofia watchdog code to see if sofia is behaving, then if the number of iterations is above IREG_SECONDS constant it fires off the registration check in the database (which also kicks off options pings). IREG_SECONDS seems to be set at 30… mod_sofia.h: #define IREG_SECONDS 30 The word "seconds" would make me think it should fire reliably every +/- 30 seconds. But it's firing every 45. The system isn't really that busy otherwise IMHO. So I am perplexed if the math is just wrong in this loop or if I'm misunderstanding this code. I'm trying to figure out how the timer is counted, looks like it's tied to the microseconds of the current clock so this should be pretty accurate, busy or not busy: switch_interval_time_t sleepy_time = !statements ? 1000000 : switch_micro_time_now() - last_commit - profile->trans_timeout*1000; if (sleepy_time < 1000 || sleepy_time > 1000000) { sleepy_time = 1000; } What am I missing here…? Just looking for root cause possibilities, happy to poke around at some settings before mucking up the code with debug statements and the like… - Darren Schreiber

FreeSWITCH Conference Call Tomorrow
by Michael Collins 10 Jul '12

10 Jul '12

Hello Community! Just a friendly reminder: our conference call is scheduled for 1PM Eastern/10AM Pacific time tomorrow. The agenda is here: http://wiki.freeswitch.org/wiki/FS_weekly_2012_07_11 Dave Kompel (drk__) will be discussing Windows firewall security. Rumor has it that he's got an interesting example of how to do server push notification for those of you who want to see an example of how to do server updates to a browser. On the ClueCon front we just wanted to remind those of you who will be in Chicago for ClueCon that Anthony will be enjoying birthday number 40-something, so plan accordingly. :) Thanks! -MC

FreeSWITCH Weekly News and Notes
by Michael Collins 09 Jul '12

09 Jul '12

Greetings all! We are back to a full week after taking last Wednesday off. This week<http://wiki.freeswitch.org/wiki/FS_weekly_2012_07_11?cc12-0709>we have Dave Kompel scheduled to talk to us on a subject that has been of much interest in recent weeks: firewall security on Windows deployments of FreeSWITCH. Many of you know that we have fail2ban<http://wiki.freeswitch.org/wiki/Fail2ban?cc12-0709>available for Linux/Unix based installs, but what about Windows <http://xkcd.com/528?cc12-0709>? There are indeed techniques for Windows systems to update the Windows firewall to prevent things like the friendly scanner <http://www.freeswitch.org/node/343?cc12-0709>. Recall: the friendly scanner is an abuse of a SIP testing tool called SIPVicious<http://blog.sipvicious.org?cc12-0709>. People use it for nefarious purposes, so having the ability to lock down the source IP address on the fly is a powerful technique to employ. We look forward to this discussion <http://xkcd.com/841/>. We are happy to report that we have a new GOLD sponsor at ClueCon: Flowroute<http://www.flowroute.com?cc12-0709>! The folks at Flowroute have graciously offered to make sure that our attendees are well taken care of. First, they are supplying the gift bags that all of our attendees will receive. In those bags will be lots of goodies from Flowroute and our other sponsors<http://www.cluecon.com/sponsors?cc12-0709>. A special item will be a $25 gift card for Flowroute. Additionally, Flowroute is sponsoring a pizza party on Monday night, August 6 at Gino's<http://www.ginoseast.com?cc12-0709>in downtown Chicago! We hope you all will be able to join us. Only a few more weeks until we're all together again! -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE

How to build Debian packages with Sangoma module included?
by Craig Ayliffe 04 Jul '12

04 Jul '12

Hi, Just wondering if anyone has been able to build Debian packages of FS with mod_sangoma_codec package built as well? I have removed it from the list of avoid_mods in debian/boot, and it goes to build it but fails because it can't find the Sangoma libraries when compiling. I am not sure how to get those libraries included in the fakeroot when it builds the packages. Any hints/assistance would be great thanks (Sorry if this should be in the user list but assumed this was the right one) -- Craig Ayliffe
