[Linphone-developers] patch to add zrtp-hash support to linphone |

With some assistance from Werner Dittmann and Guillaume Beraudo, I've created
patches to add zrtp-hash support to Linphone. At present this will add the hash
of the ZrtpHello message to outgoing SDP messages but will not verify an
incoming hash. Assuming the patches are accepted I'll add support for
verification as well.
These patches (one to Linphone and one to its oRTP submodule) will allow
Linphone to use ZRTP when connected to Freeswitch in proxy-media mode.
Freeswitch contains special case logic that looks for the 'zrtp-hash' attribute
in the SDP media definition of two clients and assigns the same SSRC to each
channel. Without it, ZRTP fails because the SSRC gets changed and the internal
packet hash will not match.
To the linphone developers: I've tried to match your style and coding standards
to the best of my ability, but if there are any problems, please let me know.
There are brief comments attached to most of the changes but I can expand upon
them, or if you wish to make modifications I'd be happy to test them.
