Install and run ============ It is possible to install Jigasi along with Jitsi Meet using our [quick install instructions] or do this from sources using the instructions below. [quick install instructions]: https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-install.md 1. Checkout latest source: ``` git clone https://github.com/jitsi/jigasi.git ``` 2. Build: ``` cd jigasi mvn install -Dassembly.skipAssembly=false ``` 3. Extract - choose either `jigasi-linux-x64-{version}.zip`, `jigasi-linux-x86-{version}.zip` or `jigasi-macosx-{version}.zip` based on the system. ``` cd target/ unzip jigasi-{os-version}-{version}.zip ``` 4. Configure a muc component in your XMPP server that will be used for the brewery rooms. If your server is Prosody: edit /etc/prosody/prosody.cfg.lua or the appropriate file in /etc/prosody/conf.d and append following lines to your config (assuming that domain 'meet.example.com'): ``` Component "internal.auth.meet.example.com" "muc" storage = "memory" modules_enabled = { "ping"; } admins = { "focus@auth.meet.example.com", "jigasi@auth.meet.example.com" } muc_room_locking = false muc_room_default_public_jids = true ``` 5. Setup SIP account Go to jigasi/jigasi-home and edit sip-communicator.properties file. Replace ```<>``` tag with SIP username for example: "user1232@sipserver.net". Then put Base64 encoded password in place of ```<>```. 6. Setup the xmpp account for jigasi control room (brewery). prosodyctl register jigasi auth.meet.example.com topsecret Replace ```<>``` tag with Base64 encoded password (topsecret) in the sip-communicator.properties file. 6. Start Jigasi ``` cd jigasi/target/jigasi-{os-version}-{version}/ ./jigasi.sh --domain=meet.example.com ``` After Jigasi is started it will register to the XMPP server and connect to the brewery room. Supported arguments: * --domain: specifies the XMPP domain to use. * --host: the IP address or the name of the XMPP host to connect to (localhost by default). * --min-port: the minimum port number that we'd like our RTP managers to bind upon. * --max-port: the maximum port number that we'd like our RTP managers to bind upon. How it works ============ Jigasi registers as a SIP client and can be called or be used by Jitsi Meet to make outgoing calls. Jigasi is NOT a SIP server. It is just a connector that allows SIP servers and B2BUAs to connect to Jitsi Meet. It handles the XMPP signalling, ICE, DTLS/SRTP termination and multiple-SSRC handling for them. Outgoing calls ============== To call someone from Jitsi Meet application, Jigasi must be configured and started like described in the 'Install and run' section. This will cause the telephone icon to appear in the toolbar which will popup a call dialog on click. Incoming calls ============== Jigasi will register on your SIP server with some identity and it will accept calls. When Jigasi is called, it expects to find a 'Jitsi-Conference-Room' header in the invite with the name of the Jitsi Meet conference the call is to be patched through to. If no header is present it will join the room specified under 'org.jitsi.jigasi.DEFAULT_JVB_ROOM_NAME' config property. In order to change it, edit 'jigasi-home/sipcommunciator.properties' file. Example: Received SIP INVITE with room header 'Jitsi-Conference-Room': 'room1234' will cause Jigasi to join the conference 'https://meet.example.com/room1234' (assuming that our domain is 'meet.example.com'). Configuring SIP and Transcription ======================================= It is possible to either enable or disable the functionality of SIP and transcription. By default, the properties `org.jitsi.jigasi.ENABLE_TRANSCRIPTION=false` and `org.jitsi.jigasi.ENABLE_SIP=true` in `jigasi-home/sip-communicator.properties` enable SIP and disable transcription. To change this, simple set the desired property to `true` or `false`. Using Jigasi to transcribe a Jitsi Meet conference ================================================== It is also possible to use Jigasi as a provider of nearly real-time transcription while a conference is ongoing as well as serving a complete transcription after the conference is over. This can be done by using the SIP dial button and using the URI `jitsi_meet_transcribe`. Currently Jigasi can send speech-to-text results to the chat of a Jitsi Meet room as either plain text or JSON. If it's send in JSON, Jitsi Meet will provide subtitles in the left corner of the video, while plain text will just be posted in the chat. Jigasi will also provide a link to where the final, complete transcript will be served when it enters the room. Google configuration ==================== For jigasi to act as a transcriber, it sends the audio of all participants in the room to an external speech-to-text service. To use [Google Cloud speech-to-text API](https://cloud.google.com/speech/) it is required to install the [Google Cloud SDK](https://cloud.google.com/sdk/docs/) on the machine running Jigasi. To install on a regular debian/ubuntu environment: ``` export CLOUD_SDK_REPO="cloud-sdk-$(lsb_release -c -s)" echo "deb http://packages.cloud.google.com/apt $CLOUD_SDK_REPO main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add - sudo apt-get update && sudo apt-get install google-cloud-sdk google-cloud-sdk-app-engine-java gcloud init gcloud auth application-default login ``` Vosk configuration ================== To use [Vosk speech recognition server](https://github.com/alphacep/vosk-server) start the server with a docker: ``` docker run -d -p 2700:2700 alphacep/kaldi-en:latest ``` Then configure the transcription class with the following properly in `~/jigasi/jigasi-home/sip-communicator.properties`: ``` org.jitsi.jigasi.transcription.customService=org.jitsi.jigasi.transcription.VoskTranscriptionService ``` Transcription options ===================== There are several configuration options regarding transcription. These should be placed in `~/jigasi/jigasi-home/sip-communicator.properties`. The default value will be used when the property is not set in the property file. A valid XMPP account must also be set to make Jigasi be able to join a conference room.
Property name Default value Description
org.jitsi.jigasi.transcription.DIRECTORY /var/lib/jigasi/transcripts The folder which will be used to store and serve the final transcripts.
org.jitsi.jigasi.transcription.BASE_URL http://localhost/ The base URL which will be used to serve the final transcripts. The URL used to serve a transcript will be this base appended by the filename of the transcript.
org.jitsi.jigasi.transcription.jetty.port -1 The port which will be used to serve the final transcripts. Its default value is -1, which means the Jetty instance serving the transcript files is turned off.
org.jitsi.jigasi.transcription.ADVERTISE_URL false Whether or not to advertise the URL which will serve the final transcript when Jigasi joins the room.
org.jitsi.jigasi.transcription.SAVE_JSON false Whether or not to save the final transcript in JSON. Note that this format is not very human readable.
org.jitsi.jigasi.transcription.SAVE_TXT true Whether or not to save the final transcript in plain text.
org.jitsi.jigasi.transcription.SEND_JSON true Whether or not to send results, when they come in, to the chatroom in JSON. Note that this will result in subtitles being shown.
org.jitsi.jigasi.transcription.SEND_TXT false Whether or not to send results, when they come in, to the chatroom in plain text. Note that this will result in the chat being somewhat spammed.
Call control MUCs (brewery) ======================================= For outgoing calls jigasi by default configures using a control room called brewery(XMPP MUC). To configure using MUCs you need to add an XMPP account that will be used to connect to the XMPP server and add the property `org.jitsi.jigasi.BREWERY_ENABLED=true`. Here are example XMPP account properties: ``` net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1=acc-xmpp-1 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.ACCOUNT_UID=Jabber:jigasi@auth.meet.example.com net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.USER_ID=jigasi@auth.meet.example.com net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.IS_SERVER_OVERRIDDEN=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.SERVER_ADDRESS= net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.SERVER_PORT=5222 #net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.BOSH_URL=https://xmpp_server_ip_address/http-bind net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.ALLOW_NON_SECURE=true #base64 AES keyLength:256 or 128 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.PASSWORD= net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.AUTO_GENERATE_RESOURCE=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.RESOURCE_PRIORITY=30 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.KEEP_ALIVE_METHOD=XEP-0199 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.KEEP_ALIVE_INTERVAL=30 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.CALLING_DISABLED=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.JINGLE_NODES_ENABLED=false net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.IS_CARBON_DISABLED=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.DEFAULT_ENCRYPTION=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.IS_USE_ICE=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.IS_ACCOUNT_DISABLED=false net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.IS_PREFERRED_PROTOCOL=false net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.AUTO_DISCOVER_JINGLE_NODES=false net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.PROTOCOL=Jabber net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.IS_USE_UPNP=false net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.IM_DISABLED=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.SERVER_STORED_INFO_DISABLED=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.IS_FILE_TRANSFER_DISABLED=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.USE_DEFAULT_STUN_SERVER=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.ENCRYPTION_PROTOCOL.DTLS-SRTP=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.ENCRYPTION_PROTOCOL_STATUS.DTLS-SRTP=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.OVERRIDE_ENCODINGS=true net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.G722/8000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.GSM/8000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.H263-1998/90000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.H264/90000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.PCMA/8000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.PCMU/8000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.SILK/12000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.SILK/16000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.SILK/24000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.SILK/8000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.VP8/90000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.iLBC/8000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.opus/48000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.speex/16000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.speex/32000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.Encodings.speex/8000=0 net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.BOSH_URL_PATTERN=https://{host}{subdomain}/http-bind?room={roomName} net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.DOMAIN_BASE=meet.example.com net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.BREWERY=JigasiBrewery@internal.auth.meet.example.com ``` The property `BOSH_URL_PATTERN` is the bosh URL that will be used from jigasi when a call on this account is received. The value of `BREWERY` is the name of the brewery room where jigasi will connect. That room needs to be configured in jicofo with the following property: `org.jitsi.jicofo.jigasi.BREWERY=JigasiBrewery@internal.auth.meet.example.com` or in the new jicofo config: `hocon -f /etc/jitsi/jicofo/jicofo.conf set jicofo.jigasi.brewery-jid '"JigasiBrewery@internal.auth.meet.example.com"'` Where prosody needs to have a registered muc component: `internal.auth.meet.example.com`. You can configure and per XMPP account callstats account, a jigasi instance can serve several deployments/domains: ``` net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.CallStats.appId=... net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.CallStats.keyId=... net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.CallStats.keyPath=/etc/jitsi/jigasi/ecpriv.jwk net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.CallStats.conferenceIDPrefix=meet.example.com net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.CallStats.jigasiId= net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.CallStats.STATISTICS_INTERVAL=60000 ``` The configuration for the XMPP control MUCs that jigasi uses can be modified at run time using REST calls to `/configure/`. # Adding an XMPP control MUC A new XMPP control MUC can be added by posting a JSON which contains its configuration to `/configure/call-control-muc/add`: ``` { "id": "acc-xmpp-1", "ACCOUNT_UID":"Jabber:jigasi@auth.meet.example.com@meet.example.com", "USER_ID":"jigasi@auth.meet.example.com", "IS_SERVER_OVERRIDDEN":"true", ..... } ``` If a configuration with the specified ID already exists, the request will succeed (return 200), but the configuration will NOT be updated. If you need to update an existing configuration, you need to remove it first and then re-add it. # Removing an XMPP control MUC. An XMPP control MUC can be removed by posting a JSON which contains its ID to `/configure/call-control-muc/remove`: ``` { "id": "acc-xmpp-1" } ``` The request will be successful (return 200) as long as the format of the JSON is as expected, and the connection was found and removed.
