small correction for my previous answer: For "outbound" only channels the command would have to be like: Show channels count like external What would result in: api = freeswitch.API(); filter = " like external"; -- set this as needed or let empty for no filter num_channels = api:executeString("show channels count" .. filter); digits = api:execute("regex", num_channels .. "|/([0-9]*)/|$1"); freeswitch.consoleLog("info", "num channels is: " .. digits .. "\n"); as already mentioned this would expect a profile for outbound calls "only", called external. More info about the filter see here: https://freeswitch.org/confluence/display/FREESWITCH/mod_commands and search for "show channels" This applys to FreeSwitch 1.6/1.7 -----Ursprüngliche Nachricht----- Von: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] Im Auftrag von Marcel Haldemann Gesendet: Dienstag, 26.

"|/([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). _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org http://www.freeswitchsolutions.com Official FreeSWITCH Sites http://www.freeswitch.org http://confluence.freeswitch.org http://www.cluecon.com FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
