[OpenSIPStack] Contribute changes to OpenSIPStack?

[Matthias D. <mdr...@gm...>]

Hello,

I did some changes to OpenSIPStack. Now my question is if it is possible 
to contribute patches?

OpalOSSEndPoint.h.patch: replaced private with protected in 
OpalOSSUserAgent to use derived SessionManager.

RegisterSessionManager.cxx.patch: moved creation of "registry" folder to 
AddRegistrationRecovery(..) so it is only created if really needed.

Regards,
Matthias
