[Freeswitch-users] Limit max concurrent calls on gateways in lua

[Stanislav Sinyagin]

the "limit_usage" command should work -- also from fs_cli.

When the "limit" dialplan application changes the current count, a
corresponding message is printed into debug log, so you should see if
the limit is set correctly during the call.
