I sent mail to libzrtpcpp developer, he answered that
disabling elliptic curve stuff is not a good idea (libzrtpcpp built now without EC).
Other distributins seem to have no problem with it because openSSL
not use any of the patented enhancements for elliptic curve computations.
I know, some time ago there were discussions about this. However, Certicom
lost the law suits regarding their ECC patents. For more infor please
So, if openSSL does not use patented ECC algorithms then maybe it
can be re-enabled in openssl package?

Not at this time. I am researching this issue, and hopefully we will be
able to enable ec in the future.
