Hi Recently, a client has asked me to do a custom application to manage intercoms.

I am trying to Sip Register and I get the challenge from the server. So I need to use the MD5 algorithm on the nonce and then send that to the server to authenticate.

I developed a SIP stack for my company. It's far from perfect, a it's lacking a lot of things from the RFCs, but it's functional and work well with a lot of tested softphones and other SIP hardware and software.
