Free mobile H.323 endpoints

While it is hard to find good H.323 endpoints for PCs that are free, there are a number of free mobile apps available that work very well with GnuGk.

Polycom RealPresence Mobile (iOS and Android)

Skip the login for the RealPresence server and set a gatekeeper in the H.323 settings.
