SIP based file transfer

Dear Maillinglist!

I would like to start implementing a (sip based) file
transfer feature, 
but I am not quite sure where to start. I  thought about 
extending the 
Instant Messaging Classes. It seems as if they already offer
a lot of 
SIP logic. Furthermore it seems as if the classes were
already prepared 
to send messages of image MIME types.

I also noticed that there is already an Interface for
sending files 
(OperationSetFileTransfer) which needs to be implemented.

Please let me know what you think about this idea and the
way of 
implementation.

Hi Martin,

I think that your project is a very good idea. File
transfert for SIP 
will really be a good improvement for SC.

To implement the file transfer in SIP you have to implement
the 
OperationSetFileTransfer interface. The instant messaging
class is just 
handling the message exchange capacity and should not be
used for the 
file transfer.

For any SIP message, we're using a sip stack named jain-sip
which will 
help you to forge some SIP messages easily (you can have
some examples 
on how to use it by looking at the implementations of IM,
telephony and 
presence).

Perhaps Emil could help you more than I do.

Hi all,

Just to inform you that some guys already worked on the file
transfer:

http://www.sip-communicator.org/index.php/Deve
lopment/FileTransfer

I remember that we talked about it with Emil and he should
have some  
source code he didn't commited, so i suggest you to wait
until he  
answers here
