Conference CDRs via http
by Mariusz Czulada 04 Dec '12

04 Dec '12

Hi all, I was thinking about sending CDRs via HTTP in a same or similar way mod_xml_cdr does. I consider implementing this (unless someone else is working on it) but first wanted to discuss with you the best approach. A. All in mod_conference This would require to copy many fragments of code from mod_xml_cdr into mod_conference. Also same configuration parameters used in xml_cdr must be processed and used for sending data. The advantage for this solution is that everything related to this mechanism is included in this module. Drawback: if something in mod_xml_cdr requires fixing or extending, probably the same changes should by applied in related parts of mod_conference. B. mod_conference builds, mod_xml_cdr sends data For this solution I'll give more details. 1. New event type should be added (like SWITCH_EVENT_CDR) 2. When a module (in this case: mod_conference) wants to store CDR via HTTP it must fire an event of that type and: - "Event-Subclass" set (like "conference") - Only common headers are needed, plus... - "Content-Type" and "Content-Length" must be set - CDR data must be build as XML in a module and added as an event content. 3. mod_xml_cdr will listen to this event type. 4. For each event subclass which mod_xml_cdr must must react, configuration file will contain a set of params same as for generic channel CDRs. 5. If subclass matches configuration, mod_xml_cdr reads data from event content and sends them according to configuration. Changes in mod_conference: - one new parameter for each profile (like "cdr-via-event=yes|no") - if "yes" then xml must be build even if "cdr-log-dir" is unset - if "yes", then an event must be fired as described above Changes in mod_xml_cdr: - extra parameters from configuration to be parsed (like '<settings subclass="conference">....</settings>') - bind to SWITCH_EVENT_CDR - if 'Event-Subclass' matches configuration, a content of the event will be sent via HTTP (probably most of 'my_on_report' routine bellow 'try to post it to the web server' comment will be reused) A [small] drawback is that it makes an indirect module dependency, but we already have such situations (like mod_shout needed to record a conference in mp3). Advantages are: - one can create an external tool for handling this type of event (to store it directly in db or send it with other protocols) - this mechanism can be easily reused in other modules if needed; maybe in mod_callcenter, maybe in other components. No further changes in mod_xml_cdr should be needed. What is unknown to me is a maximum size of event content. Conference CDR XMLs can be quite big - will it be a problem to send it this way? I think the second solution is better and more universal but I'd like to hear your opinions about this case. Regards, Mariusz

mod_dingaling times out connection after 30 seconds
by Richard Screene 31 Oct '12

31 Oct '12

Hello, The TCP connection from mod_dingaling times out after 30 seconds and is terminated. Can you tell me what the reason for this behaviour is? Can this behaviour be put behind a configuration flag or something? As a side issue, this disconnection means that ~2 hour keep alive timer on the same connection is never invoked!!! Regards, Richard

Question about sofia_presence.c
by Gerald Weber 29 Oct '12

29 Oct '12

Hi all, i'm currently extending my list_users command to show the presence status of registered sip devices. I have a snom 360 and a bria softphone here to test with, calling one from the other shows 2 rows in sip_dialogs table so presence is basically working. Both phones have the ability to set the presence to, e.g. busy or meeting or whatever. The only problem i have is, that there is no line in sip_presence table when i change the presence on the phone (or using presence in) Digging through the code, i found that this is because of the if statement in src/mod/endpoints/mod_sofia/sofia_presence.c line 4204 Looks like a check for multiple registrations, but how is this intended to work with only one registration per user ? I changed the if to if (count > 0) for testing and i can see the correct entries in sip_registrations. I'm not quite sure if i understand the purpose of this code so i didn't raise a jira. Is this a bug ? If not, does the sip_presence table only get filled when there are more than one registration per user ? Thanks gw

Freeswitch constantly crashing when tapping using wanpipe+patched libpri+freetdm+ftmod_pritap
by George Diamantopoulos 29 Oct '12

29 Oct '12

Hello all, I've been trying to configure freeswitch for tapping a PRI line using freetdm's pritap module. It seems to be working fine (apart from a couple of warnings/errors in the console), but every a few minutes it crashes. Here's the backtrace and the log file grepped around ERRs: https://gist.github.com/3970908 I hope it's meaningful. I don't have much experience with getting backtraces... Freeswitch was compiled from git sources (master) on Oct 28th. Wanpipe version is 3.5.28. Libpri version is moy's patched 1.4.10 for passive tapping, acquired from digium's svn. OS is Gentoo amd64 stable. To install freeswitch, I used the overlay the wiki suggests adding with layman. I tweaked the ebuild a little to ensure --with-pritap is always passed in my local overlay. Thanks.

Where does lrint get changed to lrintl?
by D'Arcy J.M. Cain 26 Oct '12

26 Oct '12

In libs/spandsp/src/spandsp/saturated.h around line 129 there is a line that calls "lrint(damp)". This generates the following error on NetBSD: libs/spandsp/src/spandsp/saturated.h:129:5: error: implicit declaration of function 'lrintl' I can't find any reference to lrintl in the FreeSWITCH sources and nothing in the NetBSD include trees that would do the substitution. Looks like FreeBSD has the same confusion: # FreeBSD 7 doesn't have lrintl, but lrint will do the trick just fine # It's quite cryptic as to why the reinplace doesn't work; there's no mention # of lrintl anywhere in any source.... .if ${OSVERSION} < 800012 BROKEN= Requires lrintl, which is not present on FreeBSD 7 .endif Anyone here have any idea where this substitution is happening? -- D'Arcy J.M.

Roadmap
by D'Arcy J.M. Cain 23 Oct '12

23 Oct '12

Is the roadmap supposed to be up to date? I checked and it says that 1.2.2 is the next version but 1.2.3 is already tarballed and on the files.freeswitch.org page. Also, I don't see any target dates. Even if it is subject to change, a best guess would be useful for planning purposes. I am working on creating the NetBSD package and it would be nice to know which version I should be targetting. -- D'Arcy J.M. Cain System Administrator, Vex.Net http://www.Vex.Net/ IM:darcy@Vex.Net

Installing FreeSWITCH sounds on NetBSD
by D'Arcy J.M. Cain 22 Oct '12

22 Oct '12

I have just committed the music package for FreeSWITCH into the NetBSD pkgsrc tree. I am now working on the sounds package. I looked at the FreeBSD port (their version of our pkgsrc) and they run a sox command on the files something of like this: sox -v 0.2 <filename> -r 8000 -c 1 /tmp/<filename> The -v option adjusts the volume. Does this seem like a reasonable thing to do in general? The default adjustment (0.2) lowers it quite a bit. -- D'Arcy J.M. Cain System Administrator, Vex.Net http://www.Vex.Net/ IM:darcy@Vex.Net
