[Blink] Digest user

[Malcolm Caldwell]

Hello,

Is it possible to register to a sip server using a digest  
authentication user that is different from the sip address?

I am trying to register blink against cisco call manager.  While I  
need to register as NNNN at address.of.server.com, where NNNN is an  
extension number, I need to authenticate as a regular user.

Is this currently possible?
