SIP.UA Configuration Parameters

Parameters

uri

String - SIP URI associated to the User Agent. This is a SIP address given to you by your provider. By default, URI is set to anonymous.X@anonymous.invalid, where X is a random token generated for each UA.

wsServers

Set of WebSocket URIs to connect to. By default, the WebSocket URI is set to wss://edge.sip.onsip.com. If not specified, port 80 will be used for WS URIs and port 443 will be used for WSS URIs. This parameter can be expressed in multiple ways:

wsServers: "ws://sip-ws.example.com"
wsServers: "ws://sip-ws.example.com:8443/sip?KEY=1234"
wsServers: [
  "ws://sip-ws-1.example.com",
  "ws://sip-ws-2.example.com"
]
wsServers: [
  { // First connection attempt
    ws_uri: "ws://sip-ws-1.example.com",
    weight: 10
  },
  {
    ws_uri: "ws://sip-ws-2.example.com",
    weight: 1
  }
]

authorizationUser

Username (String) to use when generating authentication credentials. If not defined the value in uri parameter is used.

authorizationUser: "alice123"

autostart

If set to true, the user agent calls the .start() method upon being created. Default value is true.

autostart: true

connectionRecoveryMaxInterval

Maximum interval (Number) in seconds between WebSocket reconnection attempts. Default value is 30.

connectionRecoveryMaxInterval: 60

connectionRecoveryMinInterval

Minimum interval (Number) in seconds between WebSocket reconnection attempts. Default value is 2.

connectionRecoveryMinInterval: 4

displayName

Descriptive name (String) to be shown to the called party when calling or sending IM messages. It must NOT be enclosed between double quotes even if the given name contains multi-byte symbols (SIPjs will always enclose the display_name value between double quotes).

displayName: "Alice ¶€ĸøĸø"

hackIpInContact

Set a random IP address as the host value in the Contact header field and Via sent-by parameter. Useful for SIP registrars not allowing domain names in the Contact URI. Valid values are true and false (Boolean). Default value is false.

hackIpInContact: true

hackViaTcp

Set Via transport parameter in outgoing SIP requests to “TCP”. Useful when traversing SIP nodes that are not ready to parse Via headers with “WS” or “WSS” value in a Via header. Valid values are true and false (Boolean). Default value is false.

hackViaTcp: true

instanceId

String indicating the UUID URI to be used as instance ID to identify the UA instance when using GRUU.

instanceId: "uuid:8f1fa16a-1165-4a96-8341-785b1ef24f12"
instanceId: "8f1fa16a-1165-4a96-8341-785b1ef24f12"

log

Object providing the desired log behavior.

- builtinEnabled

Boolean indicating whether SIPjs should write log messages in the browser console. Default value is true.

- level

Number or String indicating the verbose level of the SIPjs log. Valid values are 3, 2, 1, 0 or "debug", "log", "warn", "error" respectively. Default value is 2 (or log).

- connector

User defined Function which will be called everytime a log is generated, according to the enabled and level options.

The function is called with the following semantics:

/*
  level: String representing the level of the log message
('debug', 'log', 'warn', 'error')

  category: String representing the SIPjs instance class firing
the log. ie: 'sipjs.ua'

  label: String indicating the 'identifier' of the class instance
 when the log level is '3' (debug). ie: transaction.id

  content: String representing the log message
*/
connector(level, category, label, content);

mediaHandlerFactory

A function(session, options) that returns an object that acts like a SIP.MediaHandler. See SIP.WebRTC.MediaHandler.defaultFactory for an example.

noAnswerTimeout

Time (in seconds) (Number) after which an incoming call is rejected if not answered. Default value is 30.

noAnswerTimeout: 120

password

SIP Authentication password (String). Default value is null.

password: "1234"

register

Indicate if a SIP User Agent should register automatically when starting. Valid values are true and false (Boolean). Default value is true.

register: false

registerExpires

Registration expiry time (in seconds) (Number). Default value is 600.

registerExpires: 300

registrarServer

Set the SIP registrar URI. Valid value is a SIP URI without username. Default value is null which means that the registrar URI is taken from the uri parameter (by removing the username).

registrarServer: 'sip:registrar.mydomain.com'

rel100

Constant representing whether the UA should do 100rel. Accepts SIP.C.supported.REQUIRED, SIP.C.supported.SUPPORTED, and SIP.C.supported.UNSUPPORTED. Default value is SIP.C.supported.UNSUPPORTED.

rel100: SIP.C.supported.REQUIRED

stunServers

String or Array of Strings indicating the STUN server(s) to use for IP address discovery. Values must include “stun:” or “stuns:” schema. Default value is ["stun:stun.l.google.com:19302"].

stunServers: "stun:example.org"
stunServers: ["stun:example.org", "stuns:example.org"]
stunServers: ["stun:example.org:8000"]

traceSip

Indicate whether incoming and outgoing SIP request/responses must be logged in the browser console (Boolean). Default value is false.

traceSip: true

turnServers

Object or Array of Objects indicating the TURN server(s) and corresponding username and password to be used for media relay. ‘url’ values can include “turn:” or “turns” schema. No TURN server is set by default.

turnServers: {
  urls:"turn:exam.org",
  username:"alice",
  password:"racecar"
}
turnServers: {
  urls:["turn:exam.org",
  "turn:exam.org"],
  username:"Al",
  password:"yo"
}
turnServers: [{
  urls:"turn:exam.org",
  username:"alice",

    username:"bob",
    password:"dog"
  }
]

usePreloadedRoute

If set to true every SIP initial request sent by SIP.js includes a Route header with the SIP URI associated to the WebSocket server as value. Some SIP Outbound Proxies require such a header. Valid values are true and false (Boolean). Default value is false.

wsServers: "ws://example.org/sip-ws"
usePreloadedRoute: true

The Route header will look like Route: <sip:example.org;lr;transport=ws>

wsServers: "wss://example.org:8443"
usePreloadedRoute: true

The Route header will look like Route: <sip:example.org:8443;lr;transport=ws>

userAgentString

If this is set then the User-Agent header will have this string appended after name and version.

wsServerMaxReconnection

The number of times to attempt to reconnect to a WebSocket when the connection drops. The default value is 3.

wsServerReconnectionTimeout

The time (in seconds) to wait between WebSocket reconnection attempts. The default timeout is 4 seconds.
