Hello I'm try connect asterisk to HiPath 4000 PBX over BRI trunks (S0 S2). Which card is good for using with this PBX ? At first(test) time I'm need a card with 1-2 BRI ports, then maybe 4-8 ports. Any card can be used or not ? How much connection supported on 1 port at any time ? -- Best Regards ZHECKA-RIPN
