.

Arris sip endpoints under "unknown" conditions append Authorization
Headers during a register request when a new nonce is received from
asterisk. The newest Auth Header is added to the bottom. Other brand
endpoints work fine.

A workable fix could be to use the last Authorization header instead of
the first.

Can someone program asterisk to match nonce and realm when looking for the
Authorization Header?
