[Freeswitch-dev] Multi-server registration with replication
by Tom Parrott 16 Jul '12

16 Jul '12

Hi All, I am have been running Freeswitch for a couple of years in production as a pure voice switch, without any registrations. I have now been tasked with setting up a phone system for our business across 3 offices (in 3 countries). We have SIP trunks with telecoms providers in each country (UK, US and ZA), and want to ensure that if a user dials a local number in each country that the calls are not routed to a central server first, but go out within the same country. I would also like internal extensions to work across the 3 countries, and ideally presence as well. We are using TCP SIP registrations as we have found these more reliable when users are connecting through home routers (or MS ISA firewall) which tend to mangle UDP SIP packets. Whilst I have read on the Freeswitch wiki that you can convert the presence and registration databases to MySQL and replicate them, I am unsure whether this would work when using TCP SIP, as surely the active TCP connection is with the local registration server, and so a registration server in another country could not route calls to the client. This lead me to thinking, perhaps I could use mod_event_zeromq to gather local registration events and forward them to agents on the other servers that would re-write the dialstring and insert a modified registration entry into the local server databases. This way it would cause Freeswitch to route calls for the user that occur on a remote server to the local server and use the existing TCP connection to deliver the call? I have been told I would be able open source this project. If anyone can give any pointers it would be much appreciated. Thanks Tom

[Freeswitch-dev] FreeSWITCH Weekly News and Notes
by Michael Collins 16 Jul '12

16 Jul '12

One week closer to ClueCon! Things have been very busy for the FreeSWITCH team and community. In addition to gearing up for ClueCon <http://www.cluecon.com?cc12-0716> we've all been working on our day jobs and mixing in the occasional summer vacation. We've also had inclement weather play a role in scheduling one of our weekly conference<http://wiki.freeswitch.org/wiki/Weekly_Conference_Call?cc12-0716>call presentations. Dave Kompel, one of our resident Windows gurus, had been scheduled to discuss a technique for handling the Windows firewall in a manner similar to how we use Fail2Ban<http://wiki.freeswitch.org/wiki/Fail2ban?cc12-0716>in a Linux environment, however thunderstorms in his area required his full attention on protecting and keeping his servers up and running. We will reschedule as soon as possible. This week we have scheduled Darren Schreiber from 2600hz<http://www.2600hz.com?cc12-0716>. He will be doing a follow up to his SIP 101 discussion<http://wiki.freeswitch.org/wiki/FS_weekly_2012_06_20?cc12-0716>from several weeks ago. We will be diving a bit deeper into the SIP protocol. In the initial discussion we focused most of our attention on getting SIP endpoints registered and the setup/teardown process. This week we will look at some of the other things SIP can do, like presence. We invite you to join us this Wednesday at 1PM Eastern, 10AM Pacific. In ClueCon news we are very happy to report that 2600hz is back as a Silver sponsor! In fact, the aforementioned Darren Schreiber will be giving a presentation<http://www.cluecon.com/presentation/open-source-revamping-telecom-you-want-…>at ClueCon, discussing some of the hard-earned lessons that 2600hz has learned over the past few years. If you are interested in cloud telephony then definitely be there for Darren's talk. For those who've not registered yet please keep in mind that the "bits will shift again" this Wednesday and registrants will receive four entries instead of the current eight. Register now <http://www.cluecon.com/register?cc12-0716> to maximize your opportunity to win lots of great prizes. The ClueCon countdown is already down to 21 days! We are looking forward to seeing everyone together again in Chicago. -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE cc12-0716

[Freeswitch-dev] 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" ?

[Freeswitch-dev] 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

[Freeswitch-dev] 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

[Freeswitch-dev] 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.

[Freeswitch-dev] 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
