Yes I had this on a site previously.
One (unidentified) user ringing a number and that person was complaining.
So I added in a new route (RICHT/LODR/LDAT/LDPLN) and sent that number off to the speaking clock.
So when that number was dialed the caller just got the speaking clock instead of annoying someone.
If you REG-RICHT:LRTE;
Add a new RICHT using a new RICHT number.
Say for example new RICHT 100
Add LODR 100
ADD-LODR:100,,,,OUTPULSE,SPEAKING CLOCK NUMBER HERE;
ADD-LODR:100,,,,END;
ADD-LODR:100,,,ROUTE TO SPEAKING CLOCK;
REG-LDAT of working Route
add in a new LDAT 100 with LODR 100 in it.
Add a new LDPLN with the specific number in that but send it to RICHT/LDAT 100
