This section describes the standards compliance for the communication services for Parlay X 2.1 Call notification:
The Parlay X 2.1 interface complies to ETSI ES 202 391-3 V1.2.1 (2006-12) Open Service Access (OSA); Parlay X Web Services; Part 3: Call Notification (Parlay X 2).
See http://parlay.org/en/specifications/pxws.asp for links to the specification.
The SIP plug-in for Parlay X 2.1 Call Notification is an integration plug-in that utilizes the BEA WebLogic SIP Server to connect to a SIP/IMS network. The plug-in connects to a SIP servlet executing in WebLogic SIP Server. The SIP Servlet uses the SIP API provided by the WebLogic SIP server, which in its turn converts the API calls to SIP messages.
The SIP servlet acts as both as a SIP User Agent and a SIP Proxy. Depending on which Parlay X operation and state of the call the SIP servlet acts either as a proxy or as the calling party. This means that the calling UA must use WebLogic SIP server as a SIP Proxy.
The SIP servlet uses the WebLogic SIP server, which conforms to RFC 3261.
The specification is found on http://www.ietf.org/rfc/rfc3261.txt
Note: | When a Parlay X application returns ActionValues.Route in Action.actionToPerform as a response to operations in Interface: CallDirection, record-route header is inserted in the SIP Message the in order to stay in the call path. |
