I have noticed that if you have a pm3 that isn't fully loaded with
modemcards the calls wont get routed to the next PRI in the cascade.
Instead you will receive a busy tone.
We therefore are forced to make shure that the pm3 that isn't fully
equipped with modems is last in the chain.
In an mixed ISDN/analog setup this results in ineficcient usage of the
modem-cards, preferably you would like to have a pure ISDN pm3 first in
the chain and let it svallow all the ISDN-calls.
