[Freeswitch-users] DETECT ACTIVE CHANNELS

[Marcel Haldemann]

For LUA it's (FS 1.6):
api = freeswitch.API();
num_channels = api:executeString("show channels count");
digits = api:execute("regex", num_channels  .. "|/([0-9]*)/|$1");
freeswitch.consoleLog("info", "num channels is: " .. digits .. "\n")

to get the number of active channels.


in Dialplan it could be done like this:

<action application="set" data="foo=${regex(${show channels count}|/([0-9]*)/|%1)}"/>
<action application="log" data="INFO foo: ${foo}" />


PS: If you only want outbound calls you could try:

Show channels like external

as command, you then however must have a sip profile that is only for outbound (in this case named external).
