[Asterisk-Users] Does an entry in AstDB stay after reboot?

[Min Hwan Chang]

I set up a call forwarding script in extensions.conf which uses the
AstDB but I'm wondering if I reboot the server, will the entry in
AstDB still reside?

What the script does is when a call comes in, it check to see if there
is a null value or a call forward number.  If null, it will call the
local office connections.  If there is a number, it calls that.  Now I
just need to know if I reboot the system, the current value will still
be in the AstDB, I don't want to reboot the system and then find out
the key is always getting erased.  Thanks all for the help.
