| SUBSTANTIAL CODE CONTRIBUTIONS MADE BY THE FOLLOWING PEOPLE | ||
| ----------------------------------------------------------- | ||
|
|
||
| 1. Emil Ivov <[email protected]> Contributed a Video Softphone Under GPL. | ||
|
|
||
| 2. Emil Ivov contributed the TCK for the Transaction and Dialog layer - this | ||
| is over 75% of the TCK itself. | ||
|
|
||
| 3. Jeff Keyser Contributed the Transaction layer to NIST-SIP 1.1 that was | ||
| ported to NIST-SIP 1.2. Jeff also suggested the architecture for | ||
| MessageProcessors and extensiblity that is a part of the implementation | ||
| architecture. | ||
|

| This code was developed in the Internetworking Technogies Group (ITG), | ||
| Advanced Networking Technogies Division (ANTD), the National Institute of | ||
| Standards and Technology (NIST). | ||

| CHANGES from NIST-SIP 1.1 | ||
| ------------------------- | ||
| See the change list for differences between JAIN-SIP 1.0 and JAIN-SIP 1.1. | ||
|
|
||
| Significant implementation differences - | ||
|
|
||
| 1. The NIST headers directly implement the JAIN headers. | ||
| 2. Antlr is not used in the parser. | ||
| 3. The class hierarchy for NIST SIP has been significantly altered. | ||
| Substantial input by early adopters and fearless users. | ||

||
| ACKNOWLEDGEMENTS | ||
| ----------------- | ||
|
|
||
| Marc Bednarek and Christophe Chazeau were guest researchers at NIST when | ||
| NIST-SIP 1.0 and NIST-SIP 1.1 were in development. Their contributions | ||
| are acknowledged. | ||
|
|
||
| The JAIN-SIP 1.1 API design is largely based on the NIST implementation | ||
| experiences of JAIN-SIP 1.0. The contributions of Chris Harris | ||
| from DynamicSoft (Spec Lead for JAIN-SIP 1.0) are hereby gratefully | ||
| acknowledged. | ||
|
|
||
| Design contributions to JAIN SIP 1.1 API were made by: | ||
|
|
||
| Brian O'Neill and Josh Burger from Terminal Technologies inc. | ||
|
|
||
| Dave Ferry and Ben Evans from Open Cloud inc. | ||
|
|
||
| Brad Templeton suggested that Dialog.sendBye be changed to the more | ||
| generally useful Dialog.sendRequest. | ||
|
|
||
| Emil Ivov, Brad Templeton and others requested a method to create a cancel | ||
| and Ack request for a client transaction and consequently | ||
| ClientTransaction.createCancel was added to the API. | ||
| file:./www/README.html | ||
|
|
||
| ---------------------------------------------------------------------------- | ||
| Bug Reports and enhancements for NIST-SIP 1.2 were contributed | ||
| by the following people: | ||
|
|
||
| 1. Brad Templeton noticed bugs in the Transaction/Dialog layer | ||
| Brad suggested that Dialog.sendBye be changed to a more general | ||
| Dialog.sendRequest Brad templeton noticed that the stack was | ||
| sending out a Trying immediately and thereby not giving the application | ||
| a chance to do so. | ||
|
|
||
| 2. Emil Ivov Contributed IPV6 Support. Emil Cotributed the Video Softphone | ||
| under GPL Licensing. (See acknowledgement above). Emil noticed spec | ||
| documentation bugs. Emil uncovered bugs in the transaction layer | ||
| implementation for several corner cases. Emil and Iain Macdonnell from | ||
| Sun reported a problem with SDP parsing. Emil discovered a bug in the | ||
| Server transaction implementation. Emil contributed comprehensive | ||
| state machine unit tests of the Transaction layer to the TCK | ||
| (work in progress). | ||
|
|
||
| 3. Andreas Bystr�m reported bugs in set/get methods for Authentication | ||
| headers (quotes were missing). Andreas reported bugs in the | ||
| SDP implementation. Andreas helped to unit test call flows. Andreas | ||
| found documentation bugs and reported problems and incompleteness with | ||
| the TCK. Andreas noticed problems with Acking 487. Ack should be sent | ||
| before the TU gets called. Andreas noted that CANCEL should not | ||
| contain content. Andreas noted that a dialog can change from client to | ||
| server in the middle of the dialog (for example client sends a re-invite | ||
| and puts caller on hold -- see sipping service examples draft). The | ||
| RI was not allowing this. This was fixed and tested by Andreas. | ||
|
|
||
| 4. Antonis Karydas reported bugs in the implementation of the JAIN transaction | ||
| model. Server transactions were being created with non-null TID | ||
| on reciept of invites. Antonis reported that To/From headers should | ||
| not be restricted only to use SIP urls. Antonis reported that | ||
| route sets were not properly maintained in the DialogImpl. Antonis | ||
| reported that the DefaultRouterImplementation should be able to handle | ||
| NON-SIP URLs. Antonis fixed a bug in Dialog.sendRequest() and | ||
| Dialog.createRequest(). Antonis reported several bugs in the strategy | ||
| being used for dealing with ACKs for 4xx responses. Antonis reported | ||
| a problem in handling Server transaction timeouts and posted a fix | ||
| for this problem. Antonis reported a problem in content length for | ||
| generation of responses. Antonis reported a problem with closely | ||
| spaced ACKs for CANCELed Server Transactions. Antonis reported that | ||
| CANCEL after OK was not properly handled (stack should respond OK | ||
| to cancel and not bother application. | ||
|
|
||
| 5. Beichuang reported bugs in the IM Client and presence server. BC also | ||
| noted that extension methods were not working (Dialogs were not being | ||
| created). | ||
|
|
||
| 6. Steve Crossley reported bugs in the parser and setting local/remote party | ||
| of dialog layer. Steve contributed a fix to the next hop determination | ||
| in the Dialog code that could allow it to deal with legacy systems. | ||
| Steve noticed that the short form of Refer-To was not supported in | ||
| the parser. Steve noticed that null pointers were being generated | ||
| when SessionDescriptionImpl was being cloned with null fields. | ||
| Steve reported that content length was being set to 0 when the | ||
| content of the SIP message is specified as an Object. | ||
|
|
||
| 7. Viswashanti Raj Kadiyala reported a bug and contributed a bug fix | ||
| in the initialization of the tcp message channel. Shanti also | ||
| reported a bug and contributed a bug fix for reciever tagging for | ||
| Via headers. | ||
|
|
||
| 8. Andrew Prokop reported a bug in cloning of Authentication headers. | ||
|
|
||
| 9. Bob Johnson noticed documentation bugs. | ||
|
|
||
| 10. Mark Smith noticed that there were bugs in the handling of lr in the proxy. | ||
|
|
||
| 12. Tiago Dias (Altitude software) noticed that there was a bug with | ||
| subscribe/notify processing in the proxy. Tiago noticed that | ||
| Notify processing in the proxy (presence extension) | ||
| was not returning final response immediately and contributed | ||
| a bug fix for the proxy that rectified the problem. | ||
|
|
||
| 13. Roberto Tealdi reported a problem in instantiating multiple | ||
| stacks in multi-homed hosts. | ||
|
|
||
| 14. Laurent Schwitzer noticed that events were being dropped (not delivered | ||
| to application) when request and response were closely spaced | ||
| in time. Laurent noticed that the recieved parameter was not | ||
| handling ipv6 address types. | ||
|
|
||
| 15. Stuart Woodsford (British Telecom) noticed a bug in the parsing of host | ||
| names when there are more than 3 components in the host name. | ||
|
|
||
| 16. Brian J. Collins discovered bugs in the implementation of SdpFactory. | ||
|
|
||
| 17. Dekeyzer Dmitri < [email protected] > noted that | ||
| PRACK was not updating the Dialog state and therefore route sets | ||
| were not being applied appropriately. | ||
|
|
||
| 18. Willem Romijn corrected the payload type constant for H.263 codecs | ||
| in SdpConstants.java | ||
