Patton electronic SmartNode 4110 Series manual Notification, Mode Message inbound

SmartWare Software Configuration Guide 51 • Location Service

Notification

If the gateway receives an incoming NOTIFY request, the following procedure takes place:

1.Determine to which sip interface in the context cs the request should be forwarded. This happens accord- ing the same rules as an incoming INVITE is forwarded.

2.Get Identity. All location services bound to the context sip-gateway are searched for the identity:

a.the identity matching the to-uri

b.the identity matching request-uri

c.the identity-group default

3.Get message inbound face. The identity found must have a message inbound face configured.

4.Check subscription. The option “subscription” must be set to “implicit” or “explicit”. In the case of explicit subscription the real state of the subscription is not examined. According to RFC 3265 NOTIFY requests must be handled even before subscription is completed.

5.Check event header. The event-header of the NOTIFY request must be set to “message-summary”.

6.Check content header. If present, the content header must be set to “application/simple-message-sum- mary”

7.Forward message waiting information. Forward content of NOTIFY message through call-control accord- ing normal call routing to the destination provider.

8.Return 200 OK if all of these steps are successful.

If one of these steps fails the notification fails and an according message is sent.

Incoming NOTIFY requests can be challenged to provide authentication credentials. “Inbound Authentica- tion” on page 562 for more information.

Configuration

For configuration purposes, there is a new configuration face created in the identity of the location service. The message inbound face is used to subscribe an identity on a message server and enables the reception of NOTIFY messages with message waiting information.

Mode: Identity

	Step	Command	Purpose
1	[node](identity)[name]#[no] message	Adds a new face to the identity. The no form of the
		inbound	command removes an existing face with all content
			in it.
Mode: Message inbound
	Step	Command	Purpose
1	[node](msgin)#[no] subscribe [implicit	Enables subscription implicit, explicit or disables
		explicit none]	subscription with none.
