With 24 analog extensions 2 PRI seems rather unlikely... :-) So let's assume 2xBRI = max. 4 simulatenous calls. > > We'd like to use an asterisk system to allow some calls to be routed out > > via a VoIP gateway.

As Peter S. pointed out I think he really wants to go for a Quad-BRI card that allows for NT mode, and thus put Asterisk between the old PBX and the telco. Using analog ports on the PBX is clearly not a solution to be favoured.
