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.

I know its a client error. Every other ATA/Soft phone registers properly. I
can recreate the scenery by reloading asterisk at the time the modem
registers. It can't handle not having an ACK for the REGISTER message.
Still waiting on some feedback from Arris but I can see why the reseller
doesn't want to help. They want to sell me their $80k call agent instead of
fixing the real issue at hand. I posted a small patch that increases x
until the last authorization header is reached. Then it continues to the
original subroutine/loop.
