Hi, I am trying to install FS on RHEL 7.x but i am facing issues while setting up. I am following the documentation provided on the confluence portal. https://freeswitch.org/confluence/display/FREESWITCH/CentOS+7+and+RHEL+7 Snapshot of few error messages, did not want to paste the whole error snapshot. Error: Package: freeswitch-lang-pt-1.10.5.release.8-1.el7.x86_64 (freeswitch) Requires: libspeexdsp.so.1()(64bit)Error: Package: freeswitch-application-redis-1.10.5.release.8-1.el7.x86_64 (freeswitch) Requires: libspeexdsp.so.1()(64bit)Error: Package: libks-1.2.0-13.el7.centos.x86_64 (freeswitch) Requires: libuuid-develError: Package: freeswitch-application-lcr-1.10.5.release.8-1.el7.x86_64 (freeswitch) Requires: libpq.so.5()(64bit)Error: Package: freeswitch-1.10.5.release.8-1.el7.x86_64 (freeswitch) Requires: liboggError: Package: freeswitch-application-conference-1.10.5.release.8-1.el7.x86_64 (freeswitch) Requires: libspeex.so.1()(64bit)Error: Package: freeswitch-application-fsv-1.10.5.release.8-1.el7.x86_64 (freeswitch) Requires: libspeex.so.1()(64bit)Error: Package: freeswitch-application-httapi-1.10.5.release.8-1.el7.x86_64 (freeswitch) Requires: libpq.so.5()(64bit)Error: Package: freeswitch-lang-de-1.10.5.release.8-1.el7.x86_64 (freeswitch) Requires: libspeex.so.1()(64bit) Any help would be appreciated.

Cron-like execution in FS
by Matthew Fong 10 Feb '21

10 Feb '21

I'm wondering if there's any features that allow the cron-like execution of code inside of Freeswitch, preferably with lua--or if I am stuck using the api interface and running the cron outside of freeswitch. --matt

G.722 to PCMA choppy audio
by David Villasmil 09 Feb '21

09 Feb '21

Hello all, This is driving me nuts. I'm originating a call to a voicemail, wich i then use for ASR with a lumenvox box. When the outbound leg is PCMA/PCMU, everything's fine, but if transcoding is needed, the audio being sent to lumenvox is choppy. unimrcp's config says to send PCMA. I'm attaching a raw audio file of the choppy audio. fs is 1.10 Any ideas? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Fax to extension of B number
by Grzegorz Orzeł 09 Feb '21

09 Feb '21

Hi folks, I have a FreeSwitch serving multiple services. One of them is fax2mail/mail2fax. Logic is implemented as a set of lua scripts and it works fine. I’d like extend mail2fax direction. Currently it (lua script) picks number B, tiff file and sends it directly to B using command originate as follows: originate {<_bunch_of_headers_>} sofia/service/+4812345678(a)some.domain;user=phone &txfax(<_tiff_file_path_>) XML <_some_profile_> What I’d like to do is to add possibility to dial some other extension number. Lest’s say fax is available on +4812345678 but when the call is aswered there needs to be dialed number 123. I’ve already reviewed all FreeSwitch books on safaribooks, googled but I haven't found any example… :-/ Maybe it is enough to simply add it to the call url - I mean something like: originate {<_bunch_of_headers_>} sofia/service/+4812345678,,123(a)some.domain;user=phone &txfax(<_tiff_file_path_>) XML <_some_profile_> Can you give me some hint how to do that? Thanks in advance, Grzegorz

Homebrew now on Mac M1
by mario_fs 09 Feb '21

09 Feb '21

An FYI for the people running Freeswitch on MacOS: homebrew announced 3.0.0 today <https://brew.sh/2021/02/05/homebrew-3.0.0/> which runs nativity on Mac M1 computers. I don’t plan to get one for a long time but I would appreciate anyone who tries to build freeswitch on one to let us know how it went. You’ll have to wait though, Freeswitch 1.10.5 GA and 1.10.6 Development does not build or run on Big Sur or Catalina since November. Keep and eye on the macOS status page <https://freeswitch.org/confluence/display/FREESWITCH/macOS+Installation> to check when you can build Freeswitch on macOS again. Mario G

Prevent conversion from rfc2833 to SIP INFO
by mayamatakeshi 09 Feb '21

09 Feb '21

Hi, I have a gateway inviting FS with an SDP without payload telephone-event (rfc2833). This channelA is bridged to another channelB that does support rfc2833. I noticed that in this case FS converts the rfc28333 digit from channelB to SIP INFO to channelA. The gateway doesn't support SIP INFO, but does support rfc2833 even if it doesn't advertise it (at least it does support it for outgoing calls from what was reported to me). I tried to use this before the bridge: <action application="set" data="pass_rfc2833=true"/> but behavior didn't change. Is there anything else I can try?

mod_verto, verto communicator working only with chromium-based browsers
by Stefan 07 Feb '21

07 Feb '21

Hello, I asked that before, but perhaps the question was somehow wrong formulated or I didn't provide the right details. My Problem is the following: I have a freeswitch 1.10 installation, you can find the container I use, including a configuration similar to mine, here: https://github.com/gidmoth/freeswitch-container (The readme in the etc-freeswitch folder is the one provided by the freeswitch-minimal config package in debian, but please look at the files themselfes, because I took that only as a startingpoint). I have mod_verto enabled and try to connect clients with verto communicator, build from the sources in the 1.10 release branch on signalwire/freeswitch (https://github.com/signalwire/freeswitch) It works perfectly well with chomium-based browsers, but with firefox it does not work. >From the logs it is clear, that firefox seems not to start the negotiation of a key for srtp, and then mod_verto refuses to execute the call, because the dialplan requires srtp. Here the relevant log, a failed attemt to call a conference with firefox/verto communicator as a client: ``` 2021-01-21 15:36:48.773228 [DEBUG] switch_core_state_machine.c:287 (verto.rtc/31000) State

{mod_http_cache} Is there a way to use http_remove_cache command with multiple file
by Yusuf KALAY 05 Feb '21

05 Feb '21

Hi everyone, I want to delete multiple http caches from freeswitch in one command instead of one command for each file. Is there any way to do that? I tried a separate the files with '&' or ' ', but it does not work. Like below: ->http_remove_cache http://example.com/media/hello_world.wav&http_remove_cache http://example.com/media/hello_world_2.wav Or ->http_remove_cache http://example.com/media/hello_world.wav&http://example.com/media/hello_wor… Regards Yusuf

callcenter logout on no registration
by Nathan Stratton 03 Feb '21

03 Feb '21

I am playing around with call center, and noticed many times that users will disconnect (stop registering) but be stuck in queue because they did not log out. How hard would it be to have something that runs every minute and log out all agents that are not registered? ><> nathan stratton
