I've checked on debug, the parameter values are the same on SIP Communicator
authentication:
//algorithm = MD5
//username_value = aryjunior
//realm_value = asterisk
//passwd = mypass
//nonce_value = 0fceb3ee
//nc_value = null
//cnonce_value = null
//method = REGISTER
//digest_uri_value = sip:localhost;transport=udp
//entity_body =
//qop_value = null
And on my UAC authentication:
//algorithm = MD5
//username_value = aryjunior
//realm_value = asterisk
//passwd = mypass
//nonce_value = 18e7217e
//nc_value = null
//cnonce_value = null
//method = REGISTER
//digest_uri_value = sip:localhost;transport=udp
//entity_body =
//qop_value = null
Except by the nonce value... the nonce value for my UAC returned by the
server on the first 404 response is no valid for timeout? I get the value
from the SipListener.processResponse(ResponseEvent responseEvent), by:
...
ClientTransaction clientTransaction =
responseEvent.getClientTransaction();
Response responseClone = (Response)response.clone();
...
ListIterator authHeaders = responseClone.getHeaders(
WWWAuthenticateHeader.NAME);
...
WWWAuthenticateHeader authHeader = null;
while (authHeaders.hasNext()) {
authHeader = (WWWAuthenticateHeader) authHeaders.next();
String realm = authHeader.getRealm();
System.out.println("Autenticando em "+realm+" !!!");
}
...
authorization.setNonce(authHeader.getNonce());
...
String responseStr =
MessageDigestAlgorithm.calculateResponse(
authHeader.getAlgorithm (),
user.getUsername(),
authHeader.getRealm(),
user.getPassword(),
authHeader.getNonce(),
//TODO we should one day implement those two null-s
null, //nc-value
null, //cnonce
requestClone.getMethod(),
"sip:localhost;transport=udp",
//requestClone.getRequestURI().toString(),
"",
authHeader.getQop());
authorization.setResponse(responseStr);
...
And I'm sending a lite log file with the messages generated by the client
and the asterisk server... Thanks very much!!!
