About att_xfer on caller leg
by 王聡 15 Jun '20

15 Jun '20

Hey all, I’m trying call transfer function in freeswitch using att_xfer app, the dialplan looks like: [features.xml] <extension name="att_xfer"> <condition field="destination_number" expression="^att_xfer$"> <action application="read" data="3 6 'tone_stream://%(10000,0,350,440)' digits 300000 #"/> <action application="set" data="origination_cancel_key=#"/> <action application="set" data="attxfer_cancel_key=#"/> <action application="set" data="attxfer_hangup_key=*"/> <action application="set" data="attxfer_conf_key=0"/> <action application="set" data="ringback=%(2000,4000,440.0,480.0)"/> <action application="att_xfer" data="user/${digits}"/> </condition> </extension> [default.xml] <extension name=“inbound_call”> ... <action application="bind_meta_app" data="4 b s execute_extension::att_xfer XML features”/> … </extension> <extension name=“outbound_call”> ... <action application="bind_meta_app" data="4 a s execute_extension::att_xfer XML features”/> … </extension> The transfer should work on receiver leg in inbound call and caller leg in outbound call when I push *4, and it works correctly in my test. But an annoying problem occurred. When I tried to hangup after transfer(set as *) in outbound call, the transferred user would not hangup correctly and turned into a 3-way call. I had considered if my dialplan has some problems, but the same function works well in inbound call and transferred user could hangup after a *. Any suggestion about this problem would be appreciated. Regards.

Compiling c/c++
by David Villasmil 14 Jun '20

14 Jun '20

Hello all, If anyone can help with my confusion here: Let's say i'm working on an already existing module. I've created modules in the past, this is not really my problem. My problem comes from an already existing module, let's call it my_module. In this module I'm adding a new functionality where i need to decrypt a jwt token parameter encrypted in AES. The existing module main file, the file loaded by the main freeSWITCH loader is in C., let's say something like this: #include <switch.h> #include <switch_json.h> #include <switch_stun.h> #include <jwt.h> #include "token_crypto.h" <-- This is my addition ... <some stuff goes here> at some point i do this: plaintext_len = token_decrypt( *token_encoded, plaintext ); my token_crypto.h is SWITCH_BEGIN_EXTERN_C #include <stdio.h> #include <string.h> #include <openssl/ssl.h> #include <openssl/evp.h> #include <openssl/err.h> #include <openssl/bio.h> #include <openssl/buffer.h> #include <openssl/sha.h> void handleErrors(unsigned char *ciphertext); int gcm_decrypt(unsigned char *ciphertext, int ciphertext_len, unsigned char *aad, int aad_len, unsigned char *tag, unsigned char *key, unsigned char *iv, int iv_len, unsigned char *plaintext); int token_decrypt( const char token_encoded, unsigned char *plaintext ); SWITCH_END_EXTERN_C And then the actual implementation in token_crypto.cpp I added the requirement to compile token_crypto in the Makefile.am like this: mod_mymodule_la_SOURCES = \ base64url.cpp \ token_crypto.cpp \ mod_mymodule.c The code then compiles ok, but when i try to load it i'm getting: **/usr/local/freeswitch/mod/mod_mymodule.so: undefined symbol: token_decrypt** I know the linker can't find the compiled references, but i just can't figure out how to link it all up... call me stupid, but help me out 🤔 Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Re: [Freeswitch-users] Writing Custom Verto Events to Websocket

Interesting. Do you know of a way for another service to send a msg (perhaps other than via SIP) into FS that it could proxy out this way? Does FS have a chat listener?

Gist repo to package mod_av.so on CentOS 7 announcement
by Richard Chan 13 Jun '20

13 Jun '20

Hello list, Background: my most desired module for CentOS 7 is mod_av.so 1. I am announcing a gist-repo, for doing an out-of-repo package for mod_av.so for CentOS 7, based on the official freeswitch-devel. 2. mod_av.so is not packaged as CentOS 7 does not have ffmpeg. You need to wrangle your own ffmpeg-devel, e.g. from RPMFusion 3. With ffmpeg-devel installed and this gist repo, you can package mod_av.so without rebuilding the gigantic FreeSWITCH src.rpm. Essentially, all the libtool (gcc, ld) statements for mod_av.so have been extracted from a full build and put inside this Makefile. The compiler and linker flags are consistent with those from the FreeSWITCH spec file. 4. IMPORTANT: this gist repo does not distribute source. You must still obtain avcodec.c avformat.c mod_av.c mod_av.h from the tarball or src.rpm. All comments welcome. Cheers SP

Announcing pure Python3 ESL native async rewrite of GreenSWITCH
by Richard Chan 12 Jun '20

12 Jun '20

Hi list, You may be aware of the Python ESL library GreenSWITCH here: https://github.com/EvoluxBR/greenswitch It uses greenlets/gevent for async'ness. I would like to present a rewrite of GreenSWITCH in Python3 using native async/await (no more greenlets/gevent). Trio is chosen as the coroutine runner. https://github.com/space88man/trioswitch This is a fork of GreenSWITCH, and the rewrite is being done on the aioswitch-dev branch. BTW all the heavy lifting was done by GreenSWITCH, and I am using trio to replace all the async IO handling. So far the rewrite should be functionally equivalent but has fixed JSON event handling. Like GreenSWITCH this library does not depend on the SWIG C extension. All comments welcome. Cheers SP

Writing Custom Verto Events to Websocket
by Michael Smeltzer 11 Jun '20

11 Jun '20

Hi all, Was trying to figure out how to send custom verto events to the browser via websocket and I found this old thread, which pretty much lays out what I was trying to do - but unfortunately, no responses on this. https://lists.freeswitch.org/pipermail/freeswitch-users/2015-May/112995.html Essentially wondering if there was a way to send custom events using mod_verto's WRITE functionality, similar to below, and if there was any guidance on how to do this? I tried creating an event and firing it but it doesn't seem to appear in the websocket and it seems that mod_verto is writing these events uniquely. 2015-05-12 05:18:04.470641 [ALERT] mod_verto.c:604 WRITE192.168.10.101:48165 [{ "jsonrpc": "2.0", "id": 8, "result": { "message": "CALL CREATED", "callID": "be3e35a0-ec02-5ca7-cbf8-68a8c1cd2c4c", "sessid": "48a502b3-740a-5b3d-21a4-bf9244bafb90" } }] Thanks, Mike
