Uninstalling freeswitch after compiling and installing from source
by Ravi sanyal 18 May '17

18 May '17

Hi, I made a noob mistake and ran the script for installing freeswitch from binaries without doing logs on the process and fs_cli is complaining that commands are not found. specifically, sofia status, or sofia status profile <name> but im sure that it extends further than that. I'm dont know how to get a list of the commands available. typing in help (not /help) at the prompt says it can't find a command. So i've installed it and it doesn't seem to be working, and don't know how to uninstall it. Where can i find a list of acceptable commands for the configure command? Im trying to enable sctp, but when looking through the logs for it you have a line: checking whether SCTP is supported... yes is this the same as checking with the --enable-sctp flag? (when looking at the logs for the added command there's no extra lines pertaining to enable-sctp as if you didn't specify it). I'm running the latest build from the github repository. When running this command: ./configure --enable-sctp > /home/fleetchat/config.log it keeps on displaying errors on output, but don't know if they're serious or not. ./configure: line 31222: php-config: command not found ./configure: line 31223: php-config: command not found ./configure: line 31224: php-config: command not found ./configure: line 31225: php: command not found ./configure: line 31226: php-config: command not found ./configure: line 31227: php-config: command not found ./configure: line 5306: AX_COMPILER_VENDOR: command not found rm: cannot remove 'conftest*': No such file or directory ./configure: line 19537: test: 3.16.0-4-amd64: integer expression expected ./configure: line 19819: test: 3.16.0-4-amd64: integer expression expected config.status: WARNING: 'apr-config.in' seems to ignore the --datarootdir setting rm: cannot remove 'libtoolT': No such file or directory config.status: WARNING: 'Makefile.in' seems to ignore the --datarootdir setting config.status: WARNING: 'lib/Makefile.in' seems to ignore the --datarootdir setting configure: WARNING: ** STUN support disabled ** Im sure it's somewhere but i also don't know where the configuration files should be located when building from source. i placed them in /etc/freeswitch. From memory that was where the installation instructions said they should be located. The configuration files were downloaded from the ubuntu repository command freeswitch-meta-vanilla The reason they come from the ubuntu repository is because i had freeswitch set up on ubuntu 16.04 but found out debian was the recommended OS. I'm running freeswitch on debian 8.8 now. Nathan -- *Virtual Guard Ltd* *info(a)virtualguard.co.nz <info(a)virtualguard.co.nz>*

WSS SSL errors "decryption failed or bad record mac" under load
by Luke Wahlmeier 18 May '17

18 May '17

I keep semi-regularly running into issues using the wss transport when using dtls/strp/ice. This is on the latest 1.6.17~34~0fc0946 on Debian jessie, but I am pretty sure it was happening on the last couple releases as well. It seems like something bad/wrong happens to the encrypted data going over the websocket coming from freeswitch when more then 1 websocket connection are going and so far ice/srtp/dtls also seem to be needed in the invite to duplicate it. I have tried many different languages and network/ssl stacks and keep running into this. It is always on data coming in from freeswitch on the websocket connection, and its very very random. Sometimes I will get it 20 times in a row, other times it takes thousands of connections/sessions before it happen. It also, obviously, completely goes away if I use plain ws instead wss. Here are the errors: python: SSLError: [SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:1750) c/c++ (stunnel4): SSL_read: 1408F119: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac Java: java.lang.IllegalArgumentException: Bad arguments at javax.crypto.Mac.update(Mac.java:509) at sun.security.ssl.MAC.compute(MAC.java:135) at sun.security.ssl.InputRecord.checkMacTags(InputRecord.java:265) at sun.security.ssl.InputRecord.decrypt(InputRecord.java:216) at sun.security.ssl.EngineInputRecord.decrypt(EngineInputRecord.java:177) at sun.security.ssl.SSLEngineImpl.readRecord(SSLEngineImpl.java:974) at sun.security.ssl.SSLEngineImpl.readNetRecord(SSLEngineImpl.java:907) at sun.security.ssl.SSLEngineImpl.unwrap(SSLEngineImpl.java:781) at javax.net.ssl.SSLEngine.unwrap(SSLEngine.java:624) Attached are a simple python script to do the load, my dialplan and sip_profile. The python script can take a few runs before it see the error, and I know its not completing the sip or rtp, but even if it does this still happens. I have also looked at libsofia-sip-ua/tport/ws.c and I dont see anything obvious. I am getting setup to build v1.6 head and test this any guidance on ways I can trouble shoot this better or requests for more info are very welcome. Thanks Luke

REFER for transer call handling
by Yuriy Gorlichenko 18 May '17

18 May '17

Hi. I found some examples about features.xml but it is just a part of dialplan and will be executed on the DTMF sended in call processing (am i right?), so I trying to understand how Freeswitch handles REFER. Presume i have phone with button "transfer" that sends REFER message to server. How can I associate dialplan whith REFER message arrived to server (rewrite function for it or give additional functionality). Also can i bind some codes (like in conference mode) for every call? Because in coference mode it is very cool to use: session:execute("bind_digit_action","moderator,*1,exec:execute_extension,add") session:execute("bind_digit_action","moderator,*2,exec:execute_extension,remove") for rewrite feature codes for it. Thx you for response

Dialplan conditions
by Raúl Alexis Betancor Santana 18 May '17

18 May '17

Now that I have solved the problem of loading the dialplan from the xml files ... I get to the point that it doesn't work as I expect. This is the only extension defined: <context name="default"> <extension name="t38_transcode"> <condition field="sip_h_X-T38-Transcode" expresion="^True"/> <condition field="destination_number" expresion="^(\+1|1)([2-9]\d\d[2-9]\d{6})$"> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="sip_execute_on_image=t38_gateway peer nocng"/> <action application="bridge" data="sofia/external/$1$2(a)proxy.server.tld"/> </condition> </extension> </context> I expect not to call the bridge app if there is no T38-Transcode header on the incoming INVITE request and if it is present ... that $1$2 will be filled ... but what I get on the traces is that any call fires the call to the bridge app and also that the dialled number is exactly $1$2 ... instead of the values they should have. I'm loading a minimal setup of modules, did I need to load someother one to get the conditions and the expresions to work on this simple dialplan? My modules.conf.xml file: <configuration name="modules.conf" description="Modules"> <modules> <load module="mod_syslog"/> <load module="mod_logfile"/> <load module="mod_event_socket"/> <load module="mod_sofia"/> <load module="mod_commands"/> <load module="mod_dptools"/> <load module="mod_spandsp"/> <load module="mod_tone_stream"/> <load module="mod_db"/> <load module="mod_xml_rpc"/> <load module="mod_expr"/> <load module="mod_dialplan_xml"/> </modules> </configuration> Best regards

Noob question about xml dialplan
by Raúl Alexis Betancor Santana 18 May '17

18 May '17

Hi all, till now I'm been working with pre-made setup files for FS, and now I'm trying to get a deep knowleadge of how the dialplan works. So I modifed my autoload_configs/sofia.conf.xml file and changed my dialplan param to something like this: <param name="dialplan" value="XML:/etc/freeswitch/ dialplans/t38_transcode.xml,inline:socket:127.0.0.1:8022 async full"/> The Idea is that it loads another .xml file especific task and also use a dialplan throught a socket to a daemon that handle the rest. On my t38_transcode.xml file ... very simple: <extension name="t38_transcode"> <condition field="sip_h_X-T38-Transcode" expresion="^True"/> <condition field="destination_number" expresion="^(\+1|1)?([2-9]\d\ d[2-9]\d{6})$"> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="t38_trace=true"/> <action application="set" data="sip_execute_on_image=t38_gateway peer nocng"/> <action application="bridge" data="sofia/external/$1$2(a)proxy.server.tld"/> </condition> </extension> But If I fire a call to FS like [number]@[FS_IP] from a sip testing client I get [INFO] switch_core_state_machine.c:311 No Route, Aborting What I'm doing wrong here? My target its just I want to ANY call that came in with a SIP header of X-T39-Transcode=True (market by a sip proxy elsewhere on the net) just do a T38->Ulaw transcoding saving the T38 trace, so I could inspect it later. The rest of calls coming in ... as they don't have the sip-header should end on other app. For doing the testing I disabled the socket_inline part of the dialplan string, so it have only this: <param name="dialplan" value="XML:/etc/freeswitch/dialplans/t38_transcode.xml"/> Did I miss something? ... or maybe missundestood who the xml dialplan works ?

Fax result when using mail to fax
by Bipin Patel 17 May '17

17 May '17

Hi, I have a python script that checks a mailbox for faxes to be sent, when it finds a new mail it downloads the PDF and converts to Tiff and sends via the originate command, now the problem is I can't seem to find a way to get the fax report, nor in cdr it says what happened and the originate just says ok followed by uuid of the bridge. I'm sending the fax over a fxo gateway device. Due to it going over fxo, I have no clue if the remote fax machine answered call and the only place the fax report comes is in the console. Is there a variable or anything else that can be resent to the python script telling what the result was. I tried the execute on fax successful and fail variable but they don't seem to work. My python script generates the originate command going to loopback which goes to dial plan where the actual bridge to fxo gateway happens. How are others dealing with fax report I would love to hear. Regards, Bipin

Hi Michael, Thanks for the response, so I can just exclude phrases in; etc/freeswitch/lang/en/vm/sounds.xml to stop it reading out particular options, as essentially I dont want the user ringing in to check their voicemail to not have options to record multiple greetings, just want them to be able to record one, thats only change I need 😊 Jon ---------- Forwarded message ---------- From: Michael Jerris <mike(a)jerris.com<mailto:mike@jerris.com>> Date: Wed, May 10, 2017 at 7:49 PM Subject: Re: [Freeswitch-users] voicemail_ivr examples when checking voicemail To: FreeSWITCH Users Help <freeswitch-users(a)lists.freeswitch.org<mailto:freeswitch-users@lists.freeswitch.org>> On May 10, 2017, at 2:34 PM, Jonathan Hunter <hunterj91(a)hotmail.com<mailto:hunterj91@hotmail.com>> wrote: Hey guys, Sorry for the noise! I am looking to use voicemail_ivr so I can ensure my own phrases are played and I can avoid giving the user options to record just one voicemail message (as they have the option to upload a file from our portal too). You can do all this with regular voicemail app by modifying the phrases involved and options I think. No need to do your own completely. Take a look at the phrase configs used for voicemail and voicemail config file and let us know where it might be an issue. Can this be achieved using voicemail_ivr and if so are there any examples as confluence is good but doesnt have many configuration examples if you want to miss out phrases etc. _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting(a)freeswitch.org<mailto:consulting@freeswitch.org> http://www.freeswitchsolutions.com Official FreeSWITCH Sites http://www.freeswitch.org http://confluence.freeswitch.org http://www.cluecon.com FreeSWITCH-users mailing list FreeSWITCH-users(a)lists.freeswitch.org<mailto:FreeSWITCH-users@lists.freeswitch.org> http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org -- Jonathan Hunter Technical Director /Telephony Developer M:(+44) 7917 190 438 Email:jhunter@voxboxcoms.co.uk<mailto:Email%3Ajhunter@voxboxcoms.co.uk>

Limit module using hiredis
by John Nash 16 May '17

16 May '17

I am using limit module as per https://freeswitch.org/confluence/display/FREESWITCH/mod_dptools%3A+Limit and using it to limit number of concurrent calls for a given resource (Unique ID for a group of Source IPs). I am using hiredis module and my redis server is on another box. It all seemed to run fine when I implemented but after few days of running (Freeswitch was restarted but not redis server) I saw that redis entries have minus values against keys. In what condition they will cause entries to be negative?.
