[Freeswitch-users] Help calling phrase macros from Lua

So I'm trying to develop a simple voicemail IVR. In "sounds.xml" there's a nice macro for "voicemail_message_count", but I can't seem to figure out how to get the count to feed it. Can you help? I know I can use this to get the count in JSON format: count = api:executeString("vm_fsdb_msg_count default default " .. domain .. " " .. extension .. " inbox"); But how do I get a count that I can send to that phrase macro? Confused. (And excuse my ignorance). ----- Ned Ludd
