Yes. My zapata.conf is below.
My setup is POTS - Asterisk/TDM411B - PSTN Line. While connected to another 
party if I press flash  or *0 on my analoge phone I don't get a dialtone, 
the called party does not go on hold and I don't see anything in the CLI - 
it doesn't work. It all works fine when I don't use asterisk.
