Responding to INVITE with 180 vs 183
by Ben Hood 12 Feb '15

12 Feb '15

Hi all, I'm wondering what influences Freeswitch's signalling response when it responds to an INVITE. In some instances it appears to follow this sequence: Peer -> INVITE (SDP) -> FS Peer <- 100 <- FS Peer <- 183 (SDP) <- FS Peer <- 200 (SDP) <- FS Peer -> ACK -> FS Which leads to a successful bridge between two legs. But in other instances it appears to follow the sequence: Peer -> INVITE (SDP) -> FS Peer <- 100 <- FS Peer <- 180 (SDP) <- FS Peer <- 200 (SDP) <- FS (1st attempt) Peer <- 200 (SDP) <- FS (2nd attempt) .... Peer <- 200 (SDP) <- FS (nth attempt) ....timeout I'm not 100% sure whether the remote peer (itself a SIP trunk) doesn't like the 100/180/200 sequence (as opposed to 100/183/200), so I need to find that out for myself. But I am wondering what factors influence Freeswitch's decision of what sequence signals to send in response to an INVITE. Any pointers appreciated, Ben

Strange intermittent issue with SIP signals over WebRTC
by Oleg Stolyar 12 Feb '15

12 Feb '15

Hi guys, Sorry for a long email. I ran into this strange problem a couple of time over the last year where my Freeswitch stops receiving or sending SIP signals from and to WebRTC (JsSip) profile. At the same time, SIP signals are coming through just fine on a different profile which is regular SIP. It lasted for about 15 min. When the problem was over, I saw a bunch of BYE signals being sent to the WebRTC users at about the same for all the calls that ended during these 15 min. Also, INVITEs from these users that were sent during the 15 minutes actually got through (or at least showed in the logs) after the problem cleared. I have a fairly old FS - master from July 2014 but was wondering if anyone else had this problem. There are no errors in the logs and I cannot reproduce this at will. One possibility is that the network connection is somehow holding up these signals rather than FS. So, I was wondering when during the process of sending SIP signals over WebRTC does it get recorded in the log? Is it when the sending is successful or as soon as it's attempted? This could tell me whether FS doesn't even try to send the signal during this problem period or whether it's trying but cannot get through to the network somehow. Another piece of information - calls that were connected before the problem started continued just fine and the media kept coming through.

ISDN G.722 dropouts - jitterbuffer underruns
by Thomas Auge 12 Feb '15

12 Feb '15

We're bridging webRTC to ISDN with FreeTDM and are experiencing frequent audio dropouts. On the webRTC end we've tried Opus and G.722 even with a client right next to the server. The effects are the same, so I'm fairly certain the problem is either on the ISDN end or inside FreeTDM. Unfortunately the only thing I could find that's related to the issue is a jitterbuffer underrun when this happens. I've checked every troubleshooting hint Sangoma provides and played around with every config option I could find that might even be remotely related. But other than the buffer underruns I got nothing, though that feels more like a consequence rather than the reason. There are no frame errors/losses on the wanpipe devices (ifconfig) either. Does anyone have an idea what else to check?

Hi all, A customer has asked if there is a way to forward an email transcription of a voicemail when it is FORWARDED from another user? They like the transcripts I deliver when voicemail arrives, and would like the same feature on forwarded voicemails. Is there somewhere this could be implemented? Thanks, Sean

Mod_oreka and orkaudio problem.
by Volkan Oransoy 12 Feb '15

12 Feb '15

Hi all, I am trying to setup mod_oreka with orkaudio 1.7 but I couldn't. Freeswitch with mod_oreka sends packet via UDP but I couldn't manage to make orkaudio to listen to UDP ports. Is there a point that I miss? I couldn't find anything on the web. Thanks in advance, /Volkan Here is my confix.xml for orkaudio. <config> <AudioOutputPath>/var/log/orkaudio/audio</AudioOutputPath> <CapturePlugin>libvoip.so</CapturePlugin> <CapturePluginPath>/usr/lib</CapturePluginPath> <StorageAudioFormat>gsm</StorageAudioFormat> <DeleteNativeFile>yes</DeleteNativeFile> <TrackerHostname>localhost</TrackerHostname> <TrackerTcpPort>8080</TrackerTcpPort> <CapturePortFilters>LiveMonitoring</CapturePortFilters> <TapeProcessors>BatchProcessing, Reporting</TapeProcessors> <BatchProcessingEnhancePriority>true</BatchProcessingEnhancePriority> <AudioFileOwner>tomcat</AudioFileOwner> <AudioFileGroup>tomcat</AudioFileGroup> <AudioFilePermissions>644</AudioFilePermissions> <VoIpPlugin> <PcapSocketBufferSize>8388608</PcapSocketBufferSize> </VoIpPlugin> </config>

mod_event_socket userauth command
by Борисов, Дмитрий / Dmitriy Borisov 12 Feb '15

12 Feb '15

Hi, All! I found very interesting thing while inspecting sources of mod_event_multicast.c: userauth command. As I understood, it allows to use API without system password if we add esl-password param to user definition in directory. Params esl-allowed-log, esl-allowed-events and esl-allowed-api responding for appropriate parameters of freeswitch behavior for this connection. My question is about next: can user affect on other domains in multitenant configuration if it connected to event_socket with userauth command? Can I restrict it actions to only his domain? -- with best regards, Dmitriy Borisov

Jitterbuffer debug output
by Thomas Auge 11 Feb '15

11 Feb '15

Could someone be so kind as to translate these abbreviations for me or point me to some documentation? I couldn't find anything about it ... 655: I: DEBUG len:3/7 i=843/1000 - g:789 c:842 b:0 - ts:1674565284/10466033/1674564804 - m:2(0.200000%) j:4.60% js:20/0 dr:0/-240 920: O: DEBUG 1674564964:10466031 0 Also: What exactly does the max drift config entail? How much difference in packet timing it will handle? If so, is there a good reason to keep this value significantly below the total buffer size like in the examples? Thanks! Thomas

Does using mod_curl of free-switch more preferable than lua own curl ?
by Aqs Younas 11 Feb '15

11 Feb '15

Hi, users. I have ivr based lua script which uses mod_curl of freeswitch to get response from an API. Just curious which method is more preferable to get response from API mod_curl of freeswitch or lua on curl.? Thanks

What is correct way to compile FS without optimization
by Sergey Safarov 11 Feb '15

11 Feb '15

In case like ticket FS-7214 <https://freeswitch.org/jira/browse/FS-7214> very helpful compile FS without optimization. When I add flags CFLAGS and CXXFLAGS like below compilation is breaks. Addiding option "--disable-optimization" for configure script is help me. export CFLAGS="$CFLAGS -O0" export CXXFLAGS="$CXXFLAGS -O0" make[4]: Entering directory `/home/build/rpmbuild/BUILD/freeswitch-1.4.13/src/mod/languages/mod_python' CC mod_python_la-mod_python.lo In file included from /usr/include/limits.h:26:0, from /usr/lib/gcc/x86_64-redhat-linux/4.8.2/include/limits.h:168, from /usr/lib/gcc/x86_64-redhat-linux/4.8.2/include/syslimits.h:7, from /usr/lib/gcc/x86_64-redhat-linux/4.8.2/include/limits.h:34, from /usr/include/python2.7/Python.h:19, from mod_python.c:35: /usr/include/features.h:330:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp] # warning _FORTIFY_SOURCE requires compiling with optimization (-O) Can you suggest correct way to compile FS without optimization?
