[Nice] Compatibility with MS Office Communicator 2007 R2

[Jakub Adam]

Hi,

some time ago I submitted a patch adding support for MS Office Communicator 2007 to libnice
https://bugs.freedesktop.org/show_bug.cgi?id=28215 .

As we are planning a new release of SIPE libpurple plugin (http://sipe.sourceforge.net) with voice and
video support, we would like to ask you to review the patch and give feedback if there is possibility
to add this code into next release of libnice, or how we should improve it to be acceptable for you.

This patch is mandatory to make ICE work with MSOC clients, details are provided in the bug report.

Thanks,
Jakub
