[Freeswitch-users] Different api calls from Dialplan

Hello, freeswitch-users, I've a question regarding dialplan. Is there a difference between this two function calls (made from the dialplan) for FreeSWITCH? a) <action application="set" data="api_result=${ilx_read $1}" inline="true"/> b) <action application="set" data="api_result=${ilx_read ($1)}" inline="true"/> ^ ^ The thing is on one of my boxes both calls work, and on the other only b) works Regards j
