Sounds like call waiting on the telco side of things. I have it here as
well but asterisk just shows that there is an incoming call on the isdn
line but doesn't actually ring any phones until a channel is available.

This is my problem. I don't even know it this is the right site to ask 
for it, but let's go.
I've a Asterisk box with 1.4.1 version version installed. It's equipped 
with a TDM400 with 2 FXO modules and a HFC based ISDN BRI card.
Everything goes OK, except for the following scenario:
on the PMP S0 bus of the ISDN telecom NT adapter I've connected both a 
ISDN modem and the HFC card. Now:
1. when the modem IS NOT connected, I could receive (and obviously 
answer) up to two calls and the (eventually) third one get a busy signal

(right).
2. when the modem IS connected (it's set up to use only 1 channel) I 
could receive (and answer) to only one call (right). But, if a third 
call comes in, the phone designed to ring in extension.conf rings 
(wrong!) and the calling party ears the ringing tone! If I try to 
answer, both ends ears the busy signal and the other conversations (the 
first I've responded and the modem connection still run).
What's wrong?
Thanks for any help
