What are you trying to do? Please explain your problem in more detail. The office phones and the choice of ISDN card don’t seem to be connected topics.

I want to use ISDN card as Interface between PSTN and Asterisk server, but I am not sure if the CPU will be overstained if I use a passive ISDN card,when all the 25 telephone call at the same time.

Have you had any luck seeing if passive cards will work for your application?

I’d go for such a junhanns or beronet card, they are good bang for the buck
