Yjinglechan

Latest revision as of 12:14, 4 November 2013

This module supports the Jingle protocol. The configuration file for Jingle channel module is yjinglechan.conf.

By default the module detects Yate's run mode and behaves accordingly (as a Server, if is not set, otherwise reads run mode from configuration file).

To use it in client mode disable parameter servermode from [general] section.

See in the next image a configuration of Yate Server with Jingle configured in server mode. The clients can be SIP, IAX, Jabber or H323 for one side and Jingle or other clients for the other side. In those cases the mapping of the called number must be done from routing modules.

Here is a configuration example when Yate Server is in Jingle client mode:

[edit] Server mode

By default if yjinglechan is loaded Yate will run in server mode.

The domains and resources must be set in this case.

When a call is done using just the caller number, the jingle module will choose the first domain and resource and send the information to the other module to handle the call.

For a call to reach the destination, it needs to have set a full JID (Jabber ID). If called is user@domain, then the module will request subscription and will probe user presence, to obtain a resource to call.

Yate in Jingle server mode can automatically respond to the subscription requests, and send presence information.

[edit] Client mode

In yjinglechan.conf set Yate in client mode:

[general]
servermode=no

Note: If you intend to use the jabberserver module, and you set the same domain as the server, keep in mind that the jingle channel
 will handle all jingle iq stanzas when running in server mode.
Jabberserver module must not be loaded when using Yate in client mode.

[edit] Configuration

yjinglechan.conf

; This file keeps the configuration for the Jingle channel

[general]
; Global settings of Jingle channel

; servermode: boolean: Server/client mode
; This parameter can be used to override yate running mode
; Defaults to true if yate is running in non client mode, false otherwise
;servermode=

; domains: string: Comma separated list of domains serviced by the jingle channel
; The parameter is not used in client mode
; When running in non client mode any domain should be a jabber server (sub)domain
;domains=

; resources: string: Comma separated list of resources serviced by the jingle channel
; The parameter is not used in client mode
; The first resource will be the default one (for outgoing calls)
; If this parameter is empty the module will handle all resources
;resources=

; resource_priority: integer: Resource priority for presence sent by the module
; Interval allowed -128..127
; Defaults to 0
;resource_priority=0

; jingle_version: integer: Jingle session version to use for outgoing calls
; Defaults to the newest version if missing or invalid
; Allowed values are 0 or 1
; This parameter can be overridden when routing by an 'ojingle_version' parameter
;jingle_version=

; jingle_flags: string: Comma separated list of default jingle session flags
; Available flags:
;  - noping: Don't send ping (empty session info)
; This parameter can be overridden when routing by an 'ojingle_flags' parameter for
;  outgoing calls or "jingle_flags" for incoming calls
;jingle_flags=

; accept_relay: bool: Accept a "relay" transport type even if we had another type before
; This works only with Jingle version 0 (Google Talk, libjingle)
;accept_relay=disable in server mode, enable in client mode

; singletone: boolean: Send chan tones as single characters.
; If disabled, the whole text received as chan tone(s) will be sent
 
;  in the same XML element
; Defaults to enable
;singletone=enable

; imtochantext: boolean: Send received IM messages as chan.text if a channel is found
; If disabled, an im.route message will be pushed into the engine
; Defaults to disable
;imtochantext=disable

; localip: string: Set this machine's IP address. If missing, we will try to guess one
; The local machine's IP address is used to negotiate the audio stream
;localip=

; anonymous_caller: string: Set the caller name if missing for outgoing calls
; Defaults to unk_caller
;anonymous_caller=unk_caller

; request_subscribe: boolean: Make a subscribe request before probing a remote user
;   Defaults to enable
; pending_timeout: integer: How much an outgoing call will wait for a response to a probe
;   Defaults to 10000
; The parameters are not used in client mode
; These options are used when we want to make an outgoing call and we can't do that because we don't have
;   a resource with audio capability for the called party, so we have to probe its presence
; Since we might not receive a response if the caller is not subscribed to called's party presence,
;   we should make a subscribe request first (enabling request_subscribe will do that)
; The jingle channel will wait for the time given by pending_timeout for an an appropriate response
; If no response is received within pending_timeout interval the call will be dropped
; When receiving a valid response, the jingle channel will start to negotiate the call
; pending_timeout actually extends the time an outgoing call may be in a not answered state
;request_subscribe=enable
;pending_timeout=10000

; auto_subscribe: boolean: Automatically respond to (un)subscribe requests
; The parameter is not used in client mode
; Defaults to disable
; WARNING: If auto_subscribe is enabled when the module is handling the same domain(s) as
;  the jabber server this might lead to subscription request aproval on behalf of 'real'
;  jabber users!
;auto_subscribe=disable

; stanza_timeout: integer: The timeout interval (in milliseconds) of a stanza sent by a
;  jingle session
; Session initiate and ping timeout will automatically lead to session termination
; Minimum allowed value is 10000
; Defaults to 20000 if missing or to the minimum value if invalid
;stanza_timeout=20000

; ping_interval: integer: The interval (in milliseconds) to ping the remote party of a
;  jingle session
; If enabled and the ping element fails the session will be terminated
; Minimum allowed value is 60000. Set it to 0 to disable ping
; Defaults to 300000 if missing or invalid
; If enabled, it's value must be greater then stanza_timeout
;ping_interval=300000

; resource.notify: integer: Override the priority of module's resource.notify message handler
;resource.notify=

; redirectcount: integer: Default value for outgoing calls redirect counter
; This parameter controls the behaviour of an outgoing call terminated
;  with 'redirect' reason containing a non empty target
; If non 0 the counter is decreased. If the target is an XMPP uri the call will
;  be re-executed internally.
; If the counter is 0 when terminated, the call parameters list will be filled with
;  session parameters to let the PBX deal with it.
; This parameter can be overridden from routing
;redirectcount=0

; dtmfmethod: string: Default value for the method used to send DTMFs
; Allowed values:
;  jingle: Use the jingle protocol
;  rfc2833: Send RFC 2833 DTMFs
;  inband: Generate inband tones
;  chat: Send tones as chat messages
; This parameter can be overridden from routing
;dtmfmethod=jingle

[edit] Routing

From a routing module you can route any calls like this:

jingle/user@server

A 'callerprompt' parameter may be added with a text to be sent to the called party before making the call.

[edit] Routing example

When calling 125 route to the user 'remoteuser' at server 'remotedomain.com'

 ^125$=jingle/remoteuser@remotedomain.com;callerprompt=Hello, this is a call from ME

[edit] Configuration example

You can use the Jingle channel and the Jabberclient module to make and receive calls on Jabber accounts as you can see in this article: Jabber Client With Jingle Yate Server.
