Very Computer

I want my ISDN card to dial different telephone numbers
and establish a PPP connection depending on the IP number.

For example, if I do a

   telnet aaa.aaa.aaa.aaa -> then dial number 12345
   telnet bbb.bbb.bbb.bbb -> then dial number 54321
   telnet ccc.ccc.ccc.ccc -> then dial number 99999

In the moment there a 3 IP / tetelephone number pairs.

Is it possible to do that automaticly? If not, can I
do this manually, i.e. do a script

   ppp-on_1; telnet aaa.aaa.aaa.aaa  or
   ppp-on_2; telnet bbb.bbb.bbb.bbb  ...

Sorry, but I'm completly clueless about ISDN. I'm
using RedHat 5.2. Any pointers?

Thanks in advance, Michael.
