number of PSTN telephone numbers (DID's). The Telco will send calls
destined to your DID's over your PRI to be processed by your Asterisk
Server. The PRI will allow a maximum of 23 simultaneous conversations,
whether they are inbound or outbound (your PRI can be provisioned by
your Telco for inbound only, outbound only, or both inbound and
outbound). If I understand your scenario correctly, once the calls come
in vis the PRI, they will transferred/routed to a destination via VoIP,
using an Internet and/or some network connection. In this scenario, the
PRI will only be needed for inbound calls.
Hope this helps.

Subject: [asterisk-biz] PRI confusion
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?
Im stomped =\
