1.7 Versioning and Capability Negotiation
This document covers versioning issues in the following areas:
Supported Transports: This protocol uses SOAP 1.1.
Protocol Versions: This protocol has only one WSDL port type version.
Security and Authentication Methods: This protocol relies on the Web server that hosts the application to perform authentication. The server will not allow unauthenticated clients to access the Voice Mail Settings Web Service Protocol operations.
Capability Negotiation: This protocol does not perform explicit capability negotiation. This protocol relies on the Autodiscover Publishing and Lookup Protocol, as described in [MS-OXDSCLI], to identify protocol versions and service endpoint that are applicable to a client.
