Re: [Ccrtp-devel] Understanding GPL and ccRTP

[David Sugar]

I think the safest approach is to derive srtp into ccrtp release 1.5.x.
 If there is a license issue with openssl, the 1.4.x releases will not
be effected, and will be easy to separate.  We can later clarify the
result in 1.6.x using gnutls if necessary.
