My guess is that the ddd (and any other debugger) can't read the
asterisk way of loading dynamic libraries (which is nothing more
than scanning a directory and then to dlopen(3) all the files found
in there.

What you could do is set a breakpoint in the main() just after the
libraries are loaded, then quickly set the breakpoints and then
continue. But with a threaded, hardware-based piece of software
like Asterisk I wouldn't really put my money on it working 100% all
the time.
