[Freeswitch-users] Shared licence server

Hi, Is it possible to use G729 licences on a shared server? I mean two or multiple Freeswitch devices which serve calls would acquire licences from a license server, so we could load balance the amount of licences between the two servers. How the freeswitch is communicating with the licence server? Is it a TCP or some UNIX socket? Is such a setup possible? Do someone have experience with this? Thank you, Thomas
