When Mathematica starts up, it checks across the network for another 
copy of a running Mathematica. In Version 2.2.1 and earlier, the TCP 
software for the network is loaded in a way that causes it to think 
that it needs to initialize itself. This was a reasonable thing when 
Version 2.2.1 was released, because network utilities like MacPPP 
were relatively rare. This behaviour was changed in V2.2.2. 
Mathematica now only checks across the network if your network 
software is already running.  

I would strongly recommend that you consider upgrading to the current 
version of Mathematica for the Macintosh. This version includes 
significant improvements over version 2.0 apart from improved 
behaviour with PPP and Slip software.

Most implementations of SLIP and PPP (certainly InterSLIP and MacSLIP), 
there is an option which will not dial the modem if TCP has been 
initialized. Choosing this option should prevent Mathematica from 
dialing your phone. If this doesn't work, the only thing I can 
suggest for Version 2.0 is that you disable your PPP software when 
you want to run Mathematica.

If you are interested in upgrading, contact info at wolfram.com.

I hope this helps.
