Typically, a call has two legs: an inbound and an outbound leg.
Your users will use 1 channel when they dial in to your PRI.
When they dial out, if you choose route the call back to the PRI, it will use another channel so in this scenario your capacity would be effectively divided by 2.
If however you choose to route the call through a VoIP service provider, it won't use any of your PRI channels, but it will use some of bandwith instead.

Hey guys,
I was hoping someone could clarify this for me since i've been trying to
find out for a while now to no avail. Im thinking of deploying a call
routing service through asterisk. Basically I want people to be able to
call a number through the PSTN and then call whatever extension to be
routed through a voip termination provider.
Im guessing using a PRI is the best way to do this. However, im confused
as to how it all works. Say a PRI has 23 usable channels, does that mean
that I will be able to route 23 calls at the same time or does it mean
that I would have to split 11 channels for incoming voice traffic(from
PSTN) and 11 channels for outgoing voip traffic?
