[reSIProcate] How do I setup UAS challenge Authentication on INVITE using DUM

[praveen]

Hello,

I need to setup a UAS to send challenge response to request Digest 
authentication on INVITE .
 
The example file, BasicCall.cxx sets up clientAuthManager.  This works 
fine during registration.
But during INVITE it doesn't seem to challenge for authentication.

Do I need to instantiate ServerAuthManger to have DUM negotiate 
Authentication
during INVITE reception. 

An help to guide me through this would be greatly appreciated

Thanks
