Hello,
I'm developing a UA using JAIN-SIP that connect to Asterisk server and I
can't complete an INVITE process correctly.
The dialogue I implemented is:
1. Send register
2. Received a trying and a 401 Unauthorized
3. I send a register again with the authorization header (with the nonce and
the response fields )
4. Received a TRYING and a 200 OK messages.
At this point, I received some UDP packets from the SER continuously (I
suppose I had registered correctly).
Now, I send and INVITE message (without authorization header) and I receive
a 407 Authentication failure message. I send an ACK and again an INVITE
message now, with authorization header (response) and using the nonce I
received in the last 407 message, but I always receive again 407 message as
response from the server.
I detail the authorization headers following:
*Authorization header in 407 message:*
Proxy-Authenticate: Digest realm="i2cat.net",
nonce="4b4ef99f88dede8c57be94d4c63464f9d268fbc5"
*Authorization header in INVITE message:*
Authorization: Digest username="josep.benavent",realm="i2cat.net
",nonce="4b4ef99f88dede8c57be94d4c63464f9d268fbc5",uri="
sip:xavier.ca...@i2cat.net <sip%3axavier.ca...@i2cat.net>
",response="d6b6a75c32bc237984f03ffb26d9d745",algorithm=MD5
(I incremented de CSeq number correctly with each INVITE message).
OK, I suppose my error is in the function that creates the response with a
nonce value in the INVITE message, I detail following:
MessageDigestAlgorithm digest = new
MessageDigestAlgorithm();
String responseCode = digest.calculateResponse("MD5",
this.user, response.getRealm(), this.pwd, response.getNonce(), null, null,
Request.INVITE,uri.toString(), null, null);
(Variables values are that you can see in the Authorization header in INVITE
message detail).
Does any body know what are the values I need to create a correct
responseCode? I also tried to include a Cnonce value in the
digest.calculateResponse function with any result.
Any idea will be welcome.
Thank you for your attention,
Josep Benavent
