Sending Notify event to Phones inside fs_cli?
by Rahman Duran 08 Dec '21

08 Dec '21

Hi, Can I use sendevent in fs_cli to send Notify packets to Phones (to triger restart, provision etc). I can see how to do it in event socket documentation but I could not find any info about doing it in fs_cli. fs_cli says there is no command named sendevent. Regards, Rahman Duran

Sereverless ESL and KSUUID support
by Nikolay Zaytsev 07 Dec '21

07 Dec '21

Hi Everyone, Could you please assist with those 2 questions: 1) Has anybody created an AWS serverless ESL controller for FreeSWITCH? If yes, could you please share the experience and the technology stack that was used. 2) Does FreeSWITCH support KSUUID instead of UUID? https://github.com/segmentio/ksuid Is there any roadmap for that? -Best Reagrds, Nikolay Zaytsev

302 handling with enterprise :_: dial.
by Martin Paterson 07 Dec '21

07 Dec '21

I have an issue that I’m struggling to resolve. I’ve tried this out in the vanilla config. If a bridged destination in the default context: <action application="bridge" data="user/1001@${domain_name}”/> returns a 302 Moved Temporarily then the new destination is run through the dialplan in the same default context and everything is good. In the log: [DEBUG] sofia.c:6971 Redirect: Transfering to 1003 [DEBUG] switch_ivr.c:2289 (sofia/internal/1000(a)192.168.1.226) State Change CS_EXECUTE -> CS_ROUTING [NOTICE] switch_ivr.c:2296 Transfer sofia/internal/1000(a)192.168.1.226 to XML[1003@default] However I need to call multiple destinations at once. When separating them with comma, I sometimes get “Only calling the first element in the list in this mode”. Some destinations in my case may have multiple registrations, so that’s not an option. Instead I do enterprise dial with :_: which gets round that: <action application="bridge" data="user/1001@${domain_name}:_:user/1002@${domain_name}"/> but it has the effect that if a destination returns 302 Moved Temporarily (1002 forwards to 1003 here), then it doesn’t run through the dialplan the same context, it goes to the public context and fails because the destination (1003) is an extension in the default context. The log looks like it’s handling the 302 as if it’s a new call: [INFO] sofia.c:10462 sofia/internal/1000(a)192.168.1.226 receiving invite from 192.168.1.226:5060 version: 1.10.7 -release-19-883d2cb662 64bit call-id: ee6cd84a-cca5-123a-d6a1-080027d0c8d3 [INFO] mod_dialplan_xml.c:639 Processing Extension 1000 <1000>->1003 in context public EXECUTE [depth=0] sofia/internal/1000(a)192.168.1.226 deflect(1003) I must be missing something in my understanding here – I don’t understand why the behaviour is different, but more interestingly, is there a way of getting the enterprise dial to process the 302s in the same way as when dialling one destination?

Re: [Freeswitch-users] Sereverless ESL and KSUUID support
by Nikolay Zaytsev 07 Dec '21

Thank everyone for the reply. Regarding the KSUUID, understood. For the serverless part, lamda is limited to 15 minutes, that is right. But what do you think about the following design? 1. Have a bunch of lambda functions each corresponds to a certain event. 2. No data is stored in memory all go to Dynamo DB. 3. On the event triggered from FreeSWITCH Lamda queries the Dynamo DB for the config and related call data. 4. Lambda does processing and sends the commands to FreeSWITCH 5. Lambda updates the Dynamo DB. In case you agree that the above design might work, what do you think about the tech stack to use? I was thinking about python switchio ( https://github.com/friends-of-freeswitch/switchio) but 1) In the case of using serverless there is no need to use the async approach from the ESL engine 2) I am not sure it is developed anymore Maybe vanilla python ESL will work fine in this case. Please advise. Best regards, Nikolay Zaytsev

Hi! We are getting this error on latest version of Chrome and Verto: There has been a problem retrieving the streams - did you allow access?

Mailing list is very slow?
by Antony Stone 06 Dec '21

06 Dec '21

Hi. I wonder if there any list admins here who can either explain why this list is so slow, or preferably do something about it? For example, yesterday Alexander Perkins posted a question about Media IP. The question was timed at 2021-12-02 19:19:47 UTC I received the question from the list at 20:02:17 UTC and I replied to it at 20:13:12 UTC My own reply has just come back to me from the list at 2021-12-03 15:13:13 UTC - round-trip time = 19 hours! Looking at the headers of the question and my answer, I see the following timings (all UTC): 2021-12-02 19:19:47 Question is written and sent 2021-12-02 19:19:58 Question is received by a Google mail server 2021-12-02 19:20:29 Question is received by lists.freeswitch.org from Google 2021-12-02 19:20:31 Question is received by lists.freeswitch.org from itself 2021-12-02 20:02:17 Question is received by my inbound mail server from lists.freeswitch.org 2021-12-02 20:13:12 Answer is written and sent 2021-12-02 20:13:18 Answer is received by my outbound mail server 2021-12-02 20:13:19 Answer is received by lists.freeswitch.org from my server 2021-12-03 14:35:01 Answer is received by lists.freeswitch.org from itself 2021-12-03 15:13:13 Answer is received by my inbound mail server from lists.freeswitch.org So, that's approximately 40 minutes for the question to get from the original poster to me as a subscriber, and 19 hours for my answer to do the same round trip. Does anyone know what's causing things to be so slow, and can anyone fix it?

Hi All. Is it possible to get the media IP from an invite? We have a client that does not want to accept calls into his PBX if the media IP is not in the US. Is this even possible? If so, how? Thank you, Alex

Assigning a variable with a value from a system command?
by Antony Stone 05 Dec '21

05 Dec '21

Hi. I have a need to assign a variable in vars.xml with the value output from a system command (in this specific instance "hostname -s", but I'd like to have a generic solution for future use). How can I do that? Any suggestions are welcome, as is pointing at any documentation I've so far failed to find :) Thanks, Antony. -- Having been asked for a reference for this man, I can confirm that you will be very lucky indeed if you can get him to work for you.

Serving sofia.conf via lua (updated)
by Antony Stone 05 Dec '21

05 Dec '21

Hi. Sending again with a bit of clarification - my original message hasn't hit the list yet, so I'm hoping people can reply to just this one... 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." Yes, I know that that page refers to mod_xml_curl and not mod_xml_lua but I'm pretty certain that the principle is the same, and https://freeswitch.org/confluence/display/FREESWITCH/Serving+Configuration+… seems to confirm this, although is it much thinner on examples. I do not that this page also says "there is no Lua page yet, and Lua-related docs are scattered all over the place..." :( So, anyway, 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?

Re: [Freeswitch-users] WebRTC calls one way with custom sip messages UUI
by kaleem rehman 03 Dec '21

Hi Kaiduan, thanks for looking into it. Verto looks cool. we have no restriction as to what to use. main item is to attach data to call so sip client at end user can strip and show data to agent. no need for user to login to enter credentials, we want simple "*call us"* type button which generates a call. to make it safe from attacks as server will be on cloud, we would like some sort of safety measure, either a login and pwd, which gets passed to freeswitch to verify its genuine call from a webpage or app. or some hidden message within the generate call command so freeswitch can verify and drop any calls which arent from right source so answering party doesnt get too many junk calls from random bots who discover port is open on Cloud FS.
