Forcing pages and faxes down different modems?

[Kevan Heydon <kheydon@metallica.motiv.co.uk>]

I have just installed our second modem for our HylaFax 4.0pl0 system it went 
without any problems and I can send faxes and pages through it. But the reason 
we got this second modem was purely to put faxes through for a customer so they 
are paying for the phone line and all call charges. Our first modem is used for 
paging support people when things go wrong with our system or customers 
systems. Obviously we do not want to send support pages down the second modem.

Now I can setup the SNPPSERVER environment variable to:

  cua_a@machine:444

so the correct default is used, but this can be overridden with the -h option 
on sendpage(1) so if someone here is 'playing' with this program they could end 
up sending stuff down the wrong modem. What I would like to do is disable pages 
completely from cua_b. Is this possible?

Many thanks for listening...
