"The MeetMe application needs a timer to work. There are different ways 
to get the timer to work, but it won't work by default if you haven't 
got a Digium Zaptel hardware interface card installed. At this time only 
zaptel devices may be used. If you do not have a Zaptel device see the 
ztdummy instructions for timing."

i guess you don't have digium card nor using ztdummy or such module
for timing.
