[Freeswitch-users] Managing Presence on Gateways

Hi Guys, In the external profile (as in the internal) there is an option to enable presence functionality (with setting it to passive).

Does it mean that the gateway could subscribe itself for some presence information in that domain in behaves of local users and relays them? Appreciate all comments, -- afshin
