In BT speak, Presentation numbers are not the same as DDI presentation.

All you can do is to allocate some of your DDI range as the 'main' numbers 
for each company, and then SetCallerID() to it when each company makes an 
outbound call. This will acheive what you want, but only from numbers within 
your allocated geographic range - you can't do it with 0870 numbers for 
example.
