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.
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.
- 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
