I want to use a freeDTM fxs to make local calls on a POTS line IF it isn't busy - not seeing an example of how to test. ( There are some ftdm commands for the fs_cli - but I'm not seeing how to grab this information for the dialplan.
Has someone else set up a backup line like this?
Hello Karl, You can execute CLI commands (which in FreeSWITCH lingo are called APIs) from the dialplan using dollar-sign syntax such as: <condition field="${ftdm_usage(1 1)}" expression="^0$"> </condition> That checks if span 1 channel 1 has 0 calls. Note there is an inherent small race between the time you check and the time you try to use the channel, but that ought to be good enough I think. *Moises Silva **Manager, Software Engineering*** msilva@sangoma.com Sangoma Technologies 100 Renfrew Drive, Suite 100, Markham, ON L3R 9R6 Canada t. +1 800 388 2475 (N.
