The client then sends the digest in the Digest Authentication, used both by SIP and HTTP, introduces the ability to only save an encrypted version of the password on the server. It seems that as a result, SX20 is not filling in the username (extension number) in the register message. CUCM/VCS would be able to authenticate this SX20 using those credentials if this is what it expects. The use of basic authentication, where passwords are transmitted unencrypted, is not permitted in SIP. It is a simple challenge-response mechanism that allows a server to challenge a client request and allows a client to provide authentication information in response to that challenge.
