ast_func_write: Function DB not Registered

I am trying to use the new DBput/DBGet stuff. In my dial plan I have

exten => s,n,Set(DB(SRVC/${main-phone})=${service-level})

This gives the error:

ERROR[16111]: pbx.c:1423 ast_func_write: Function DB not Registered

additionally, exten => s,n,Set(TIMEOUT(digit)=15) give the same (Function TIMEOUT not registered)

I am using the latest CVS head.

Any help is appreciated. Thanks!

Got it. Needed to add

load => pbx_functions.so

to modules.conf
