Why don't you start with something simple as:

channels() {
 lsdahdi | awk '/^ /{print $1}'  # | head -n whatever

for chan in `channels`; do
  asterisk -rx "channel originate DAHDI/$chan/something application Echo"

Alternatively, if you have a convenient way to control the number of SIP
calls coming from a certain trunk, redirect the all to DAHDI/g0 .

Simple load is very simple to generate with Asterisk.
