[jitsi-users] file trasfer size limit problems

with jitsi I have a problem.
When I attempt to send files larger than 2048MB I have an error

File size exceeds the maximum allowed for this protocol: 2048 MB.

with other clients like spark I do not have this limitation but i wanted to use only one
tool for my users and I did choose jitsi.

is it possible to overcome this limitation ?

the server is openfire 3.9.1 but itself it does not have file size limitation for transfers.

thank you
