I'm using the php esl implementation in fusionpbx.. I'm able to pass "api show channels count" and "api show calls count" and the like, but when I do:
"api limit_usage hash origination usa_pd" it's just blank.
Pasting "limit_usage hash origination usa_pd" into fs_cli yields 0 (or higher as the case may be).

There DOES seem to be a \n returned, but nothing else. I've got no 'friggin clue.
Help, please?

Thanks,
Avi
