JAIN SIP未经授权的响应

Question

I am developing a SIP client using JAIN SIP library in eclipse environment.

I am having trouble getting authorization. I have also implemented the MD5 challenge and added Authorization to the second Register function.

The authorization credentials are also correct as I checked them with available SIP application. I was able to Register and make calls with it.

This is the code for initialization and registration

String username = "username";
String server = "10.99.00.00";
String password = "password";
String realm = null ;
private String nonce = null;

// Objects used to communicate to the JAIN SIP API.
SipFactory sipFactory;          // Used to access the SIP API.
SipStack sipStack;              // The SIP stack.
SipProvider sipProvider;        // Used to send SIP messages.
MessageFactory messageFactory;  // Used to create SIP message factory.
HeaderFactory headerFactory;    // Used to create SIP headers.
AddressFactory addressFactory;  // Used to create SIP URIs.
ListeningPoint listeningPoint;  // SIP listening IP address/port.
Properties properties;          // Other properties.
ClientTransaction inviteTid;
Request request;
Response response;

// Objects keeping local configuration.
String proxy = null;
String sipIP="10.99.00.00"; 
String localIP= null;
// The local IP address.
int sipport = 5060;                // The local port.
int rport = 52216;
String protocol = "UDP";        // The local protocol (UDP).
int tag = (new Random()).nextInt(); // The local tag.

I compared both the packets and didnt find any difference. I dont understand why I am not geeting Authorized. Also the localIP and SIPIP are different in this case.

I think the problem might be with the ports but I didnt find any help on the net for assigning the rport and sipport: 5060. I would also like to get more information on it.

Answer 1

The call ids on both REGISTERs CSeq 1 and CSeq 2 should be the same. They are different in your case.
