It is possible to register to a sip provider with asterisk, namely with the command:
register => [peer?][transport://]user[@domain][:secret[:authuser]]@host[:port][/extension][~expiry]
What if what I want to do is to setup a sip provider? Not for end-clients, but for a sip-peer? Where can I define the credentials (username/password) that the peer needs to use to connect to my server?
In other words: what I want to setup is an endpoint so that a remote server can register with the register command.
