When the vital receive sip register request, it would response 401 unauthorized with the challenge as follow
WWW-Authenticate: Digest algorithm=MD5, realm=”asterisk”, nonce=”54a97f0e”
May I change the method of digest access authentication with qop(quality of protection)? So the challenge will be like that WWW-Authenticate: Digest realm=”relcmitel”,nonce=”=gs&v~f}v6SgL)niw&;@YDy|z/zzBj[Ggcce{#jf^4a{:A[j7AR:3vn/0dYa9J.!”,algorithm=MD5,qop=”auth”
Thanks in advanceĀ
