DUM Registering and Authenticating

The following bits are required in order to build an application that registers with a SIP registrar, and has the ability to respond to Digest Authentication challenges:

• You need to install a ClientAuthManager:

 mDum->setClientAuthManager(std::auto_ptr<ClientAuthManager>(new ClientAuthManager));

• You need to register a ClientRegistrationHandler:

 mDum->setClientRegistrationHandler(this);

• You need to set Digest Credentials on your active profile:

 profile->setDigestCredential(realm, user, password);
 profile->setDefaultFrom(selfAor);

• You need to implement the registration handlers you installed in step 2.
