Re: [ecf-dev] SIp Voip implementation

Hi Harshana

I am not explicitly knowledgeable about the SIP protocol. Where i could help would be in regards to the call api. Also improvements in the field of the call ui are things which need to be worked on. So if you are interested in that regards i would be happy to discuss an upcoming implementations.

Harshana,

Yes...I think both are good ideas.  It's possible, BTW, that there are some SIP impls out there among  Eclipse Foundation members that could be used/contributed to ECF.  I will do some exploration on that front...along with Roland (and Moritz if he is able).


Thanks,

Scott

Hi Scott,

Yes. I'm thinking of limiting the scope of the project to a realistic level as the protocol development will require quite some time. I will discuss this with Roland.

Thanks.

Cheers,

       Hi Scott. Hi Roland,

       It seems to be JAIN is under a Commercial license. So it
       leaves me to the only other available option of implementation
       of SIP protocol by myself. So I'm planing to implement this
       under the EPL.


   Although I have no problem with this as a proposal (SIP protocol
   implementation under EPL)...and am enthusiastic...it is a very
   ambitious idea for a GSOC project...as complete SIP
   implementations will require a significant amount of work.  You
   may want to restrict the scope somewhat for your GSOC
   project...just to make it realistic for a ~4 month project.

   My $0.02.  I would also suggest getting Roland's (and helpfully
   Moritz') input on this as well...if possible.

          Hi Scott, Hi Roland,

          Thanks for the quick response. This is really going to be a
       very
          exiting project as Scott pointed out :).

          Currently I'm looking at 2 exiting implementations for SIP
          implementations, JAIN SIP from Sun and Mj SIP. MjSIp is
       under GNU
          GPL. so I'm not going to use it as it is might create
       issues with
          Eclipse Foundation licensing. But what about JAIN SIP? I'm
          comfortable with implementing the SIP protocol by myself.
       If you
          think that my implemetation under Eclipse license would
       best way,
          i can proceed with it. So please let me know about your
       opinion on
          this.

          Roland, Yeah sure. that's a good point.  Let's have a chat
       about
          this more before we get in to a path which end up with nothing.

              Betreff: Re: [ecf-dev] SIp Voip implementation

              Hi Harshana,

              Thanks for your proposal and interest.  I think this
       would be
              a *very*
              exciting project.  We already have a Skype
       implementation of
              the ECF
              Call API, and would very much like a SIP implementation as
              well (there
              is this bug/enhancement request for this here
              https://bugs.eclipse.org/bugs/show_bug.cgi?id=193388).

              If possible, I would like to engage ECF committer
       Roland Fru
              in this
              work, as his expertise is in VOIP, SIP, etc.  Also, I would
              like to a
              previous GSOC student Moritz Post, who implemented the ECF
              call API
              using Jingle/Smack API:
                    http://wiki.eclipse.org/VoIP_via_the_ECF_Call_API_and_the_Jingle_Protocol

              Both would be great people to have involved
       with/mentoring your
              project.  I've cc'd this email to both Moritz and
              Roland...Moritz and
              Roland please respond on the ecf-dev mailing list about
       your
              interest
              and availability for mentoring Harshana's proposal.
        Ideally,
              I think it
              would be good to have both Roland and Moritz as mentors for
              this project
              so the duties can be shared and the experience of both
       of them
              would be
              useful.

              Thanks to all involved.  I think this can/will be very
       cool.

              Harshana...one question...do you expect to implement
       the SIP
              protocol
              (i.e. in java) yourself, or are you thinking/planning
       on using
              some
              existing implementation?  If you are already looking at
       existing
              implementations...then which ones?  The reason I ask is the
              issues of
              licensing/license compatibility that may/could arise
       with Eclipse
              Foundation.

              Thanks,

              Scott
