RE: [Linphone-developers] Real-time text in Linphone

[Simon Morlat]

Thank you for describing the possibilities of such a feature.
We have no plan to implement it, but a patch is always welcome.
It is higly recommended to everyone that wishes to contribute to
linphone to work with git, so that patches are still mergeable when they
are finished.

Simon
