[asterisk-dev] chan_sip: configurable peer username in digestauthentication

[Nick Lewis]

I agree that "authuser" would be suitable for this OP case (where
realm=domain) but think that in general there may be many peers in a
remote realm. Therefore perhaps there should be a conf structure (with
atomic elements please) for use with outbound authentication to realms
so that the realm based authentication can be divorced from specific
peer definitions e.g.

[remote-realm-name-1]
type=remoterealm
authuser = my-account-for-realm-name-1
remotesecret = my-password-for-realm-name-1

[remote-realm-name-2]
type=remoterealm
authuser = my-account-for-realm-name-2
remotesecret = my-password-for-realm-name-2

[peername]
etc...

Does the global_match_auth_username really do a peer match on authuser?
I had assumed that it only ensured  that the authuser rather than
userinfo part of the request-uri was used in authentication. Yelp - I
need to disable this behaviour for type=service sharpish.
