Implemented SIP Methods
This module implements the following SIP methods:
- SUBSCRIBE - Allow SIP clients to subscribe to specific events
- NOTIFY - Notify SIP clients when an event's state changed
To enable the subscribe method set:
ysipchan.conf
[methods] subscribe=yes
To configure the logic of how to handle the subscriptions and the notifications use subscription.conf file.
This module implements the abstractization between the SIP protocol and the subscriptions and register modules that handle the functions in a protocol-independent way.
Message handlers
Internally Yate will handle the following messages:
- sip.subscribe Used to generate a resource.subscribe message
- resource.notify Used to generate a xsip.generate message with method=NOTIFY
Allowed events
Use section [allow_events] to restrict/allow subscriptions to individual events. If an event is disabled, no subscriptions to it will be allowed.
The supported events are: dialog and message-summary.
Section [allow_events] has the following settings:
- default: boolean: Default value if an event is not listed here. Defaults to enable
- dialog: boolean: Enable/disable subscriptions to dialog state events. Defaults to enable
- message-summary: boolean: Enable/disable subscriptions to message waiting events. Defaults to enable
Configuration file
Configuration file sipfeatures.conf
; This file configures the SIP feature module [general] ; expires_min: int: Minimum allowed expiring time in seconds ;expires_min=60 ; expires_def: int: Default expiring time if not present in requests ;expires_def=600 ; expires_max: int: Value used to limit the expiring time to something sane ;expires_max=3600 ; forcedialogdata: boolean: Force (fill if missing) some parameters (dialog.callid, ; dialog.localtag, dialog.remotetag, dialog.remoteuri) in dialog state notification, ; if made for a valid dialog (dialog.id is not empty) ; Defaults to enable ;forcedialogdata=enable ; verbosexml: boolean: Build verbose XML bodies (add line breaks and spaces) ; A dialog XML notification body will spare about 38 chars if this option is disabled ; Defaults to enable ;verbosexml=enable [allow_events] ; Restrict/allow subscriptions to individual events ; If an event is disabled, no subscriptions to it will be allowed ; default: boolean: Default value if an event is not listed here ;default=enable ; dialog: boolean: Enable/disable subscriptions to dialog state events ;dialog=enable ; dialog: boolean: Enable/disable subscriptions to message waiting events ;message-summary=enable
