You have 2 options:
1. Openser challenges/authenticates the user
2. Asterisk challenges/authenticates the user

If you use option 2, openser has to forward the requests to Asterisk. 
Thus, ALL requests must be forwarded to asterisk as openser does not 
know if the supplied credentials are correct or not.
