I'll pass on this one. I haven't used analog lines in a long time. I do
seem to remember a write up on it but I don't remember the URL.

Depends on port density needs. A FXO daughter card on an already
deployed TDM400 card is fine if you have the space needed to install it.
An X100P card though will introduce more interupts and load to your
machine when used in conjunction with the TDM card. If you start running
out of space, you should look into a T1 card and channel bank.

In the modules.conf, use the noload option to not load the specific
modules you are not using. Consider this a must as it reduces security
concerns. While asterisk developers strive for error free code, there is
always a chance of some bug biting you before you can patch. If you turn
off all the unneeded modules, you will limit your exposure to new
potential exploits.

Top isn't a real good tool. It should however show that your system
still has resources available.

not sure about this one.

It is unlikely you will overload a server because of your configs.
