Domain Resolver API

Use the Domain Resolver API to perform DNS lookups of SIP URIs using the RFC 3263 protocol. These lookups can be performed synchronously to avoid having to preserve state in order to handle an asynchronous callback. They can also be performed asynchronously if you need a better performing interface.

The Domain Resolver API provides an interface that enables an application to perform DNS queries for SIP URIs. When the Domain Resolver API is used asynchronously, a listener is called after the DNS query completes. We can use one of the following methods in the application code to access the Domain Resolver API:

Use one of the following methods to perform the URI lookup:
