Serving sofia.conf via lua
by Antony Stone 30 Nov '21

30 Nov '21

Hi. I am trying to get Freeswitch to get its sofia configuation from lua instead of static XML files. https://freeswitch.org/confluence/display/FREESWITCH/mod_xml_curl tells me for example that "Section: configuration - This is used to send back configuration files such as sofia.conf." So, I'm pretty sure what I want to do should be possible, but nowhere have I so far been able to find a fully working example telling me how to do it. My understanding so far is that: 1. I need to create a lua script which generates the *complete* XML as would be served from /etc/freeswitch/autoload_configs/sofia.conf.xml and all its included sub-directories/files 2. This XML as output from the script should be enclosed within tags: <document type="freeswitch/xml"> <section name="configuration"> ... XML goes here ... </section> </document> 3. I should place this lua script in freeswitch's scripting directory, which on my (Debian) machine is /usr/share/freeswitch/scripts 4. I need to enable this script to be run by including in /etc/freeswitch/autoload_configs/lua.conf.xml: <param name="xml-handler-script" value="sofia.conf.lua"/> <param name="xml-handler-bindings" value="configuration"/> The first thing which is not clear to me is what I should do about /etc/freeswitch/autoload_configs/sofia.conf.xml - if I leave it as it is, it appears to be used in the normal way, and my lua script is ignored - if I delete it (or rename it to sofia.conf.xml.noload for example) then sofia doesn't get loaded *at all* and when I go into fs_cli I do not even have a "sofia" command - if I "touch" the filename so that /etc/reeswitch/autoload_configs/sofia.conf.xml exists but is empty, I get the same result egain - the "sofia" command does not even exist in the cli So, can anyone point me at how to join these things up correctly so that I can serve sofia configuration settings from a lua script?

Freeswitch video playback re-invite
by Volodymyr Fedorov 29 Nov '21

29 Nov '21

Hi, I have a question. Is there any way to trigger re-invite, if video playback is requested? for example I have following extension: <extension name="videoplayback"> <condition field="destination_number" expression="^6054$"> <action application="answer"/> <action application="playback" data="voicemail/vm-goodbye.wav"/> <action application="playback" data="/opt/video/lipsync.mp4"/> </condition> </extension> I think Freeswitch should do re-invite with video codecs in SDP, but it does not. Maybe I missed something? I checked examples of config: https://github.com/signalwire/freeswitch/blob/master/conf/testing/dialplan/… And so far did not find an answer to how to trigger re-invite. Thanks! -- Best regards, Volodymyr

Lua to create gateway XML
by Steve Aubrey-Bradshaw 29 Nov '21

29 Nov '21

Hi, I'm trying to use a Lua script to manage a list of SIP gateways on FreeSwitch that are stored in a mysql database. I have a script that I can run from the CLI that prints out the correct XML and I've added the lines below to autoload_configs/lua.conf.xml <param name="xml-handler-script" value="gateways.lua"/> <param name="xml-handler-bindings" value="configuration"/> However, nothing from the script is loading. I suspect that I'm not returning the XML from the script correctly. I'm currently using stream:write Does anyone have any experience with this? Best Regards, Steve

FusionPBX - Cannot queue any more events
by Glen G 28 Nov '21

28 Nov '21

Hi, I'm running FusionPBX 4.4 and have recently starting getting the following message: *[ERR] switch_cpp.cpp:48 Cannot queue any more events* This system system load is quite low max 20 calls per second and max 60 calls, hosted on AWS (very low CPU and RAM utilization) I've read on other posts that the issue here would be with a script that is consuming events but not processing them quickly enough. I'd like to get pointed in the right direction to track down what script this might be, is there some debug or logging mode I can enable to track this down? Thanks.

Re: [Freeswitch-users] WebRTC calls one way with custom sip messages
by David P 27 Nov '21

27 Nov '21

If you use Verto, you will need to embed the userID and password of a Freeswitch user in the page resources so it can be passed in the $.verto.init(...) call. You can protect this signaling channel somewhat by rotating the password frequently. However, I don't know if there is any way to protect the large range of ports that FS needs to be open to handle exchange of audio and video. I asked here a few weeks ago if it would be possible to configure FS to ignore requests on these ports from all addresses except those that have an active login on the signaling channel.

WebRTC calls one way with custom sip messages UUI
by kaleem rehman 25 Nov '21

25 Nov '21

Hi All, our requirement is simple, we will have CALL US button on website when they click, we want a call generated to our FS Server via WebRTC (no need for calls from FS to Users, it will be one way only from User to Server. With call we want to send additional data like URL of page they on, login if they are logged in. we can get data like URL and userlogin but want to sent it with SIP call as SIP Message (Probably as USER to USER Information) so we can pull at other end. any ideas of achieving this Thanks, Kaleem

originate api: Escaping variable names/values
by Shane Mitchell 23 Nov '21

23 Nov '21

Using the originate API and enterprise origination: I am attempting to specify various variables, such as custom headers and digest credentials, and am trying to understand how escaping is implemented, as I am inserting user-specified values into the string. I need to set it all up in one API call due to the various ways originate is being used. Here's a simple example: originate [sip_h_X-Custom=ESCAPED]sofia/public/user(a)example.com $park() I have searched the docs and source code, and have a solution that works most of the time, but there are edge cases I can't seem to resolve. I've tried URL encoding but it seems to have no effect here. Escaping with back-slash seems to have an effect, so I've experimented with it below. For example, this works: Escaped: \'123 (inserted in above API command) Actual: '123 (the value of X-Custom observed in the generated INVITE) Expected: '123 While this doesn't: Escaped: \'1\'23 Actual: 123 Expected: '1'23 In fact, for an even number of quotes, none survive, while for an odd number of quotes, only the last quote ever survives: Escaped: \'1\'2\'3 Actual: 12'3 Expected: '1'2'3 Escaped: \'1\'2\'3\'4\'5\'6\'7\'8\'9 Actual: 12345678'9 Expected: '1'2'3'4'5'6'7'8'9 Wrapping the entire argument with single quotes does not change the behavior: Escaped: '\'1\'2\'3\'4\'5\'6\'7\'8\'9' Actual: 12345678'9 Expected: '1'2'3'4'5'6'7'8'9 Besides single quotes, backslashes also act strangely. Many times they work properly: Escaped: a\\b\\c Actual: a\b\c Expected: a\b\c But when escape sequences are in a sequence, they act unexpectedly: Escaped: \\\\ Actual: \ Expected: \\ Escaped: a\\\'b Actual: a'b Expected: a\'b The next example becomes truncated. My guess is that it is interpreting "\n" as a new line. Escaped: a\\nice\\day Actual: a Expected: a\nice\day Can anyone advise if I'm using the correct syntax/this is an issue, or if there's something I'm missing/doing wrong? Version: FreeSWITCH Version 1.10.7-release-19-883d2cb662~64bit (-release-19-883d2cb662 64bit)

Hi, I'm running centos 7 and trying to enable mod_perl (it's required astpp to run). I've installed both via yum and built from source with the latest freeswitch. When I enable mod_perl freeswitch crashes with a coredump (see below) freeswitch(a)localhost.localdomain> load mod_perl 2021-11-23 11:26:01.754985 99.70% [INFO] switch_stun.c:897 External ip address detected using STUN: removed 2021-11-23 11:26:01.974836 99.70% [INFO] switch_stun.c:897 External ip address detected using STUN: removed 2021-11-23 11:26:02.054927 99.70% [INFO] mod_enum.c:887 ENUM Reloaded 2021-11-23 11:26:02.054927 99.70% [INFO] switch_time.c:1430 Timezone reloaded 1750 definitions 2021-11-23 11:26:02.074919 99.70% [INFO] mod_perl.c:518 Allocated perl intrepreter.

Which is right mailing list?
by TTI 22 Nov '21

22 Nov '21

I'm starting to interact with FS programmatically (in C) and need some advice. Is this the right mailing list? I see a freeswitch-dev list, is that for developers using FS, or developers creating FS?
