[Freeswitch-users] mod_snom dialplan demo not working

I'm trying to replace our aging nortel system with a FreeSWITCH based system using snom 3[267]0 phones. I've been doing okay so far but I'm running into a brick wall when I try to run the mod_snom demo in the dialplan. I've setup the 'line 2' function key to type button with the number being 'message' like it says on the snom wiki and when I dial extension 9000 the button lights up, but pressing the button does absolutely nothing. I can't figure out what I'm missing here. Any advice? Andrew
