Hello, we are a firm who wants to develop some VOIP solutions. The first infrastucture we choose for development is: - an Asterisk machine connected to a traditional PBX (s0). In this way people is not (yet) obligated to migrate its extisting PBX (and analog phones) to VoIP. - The PBX will be then configured to redirect specific outgoing calls (i.e. a remote branch office) to Asterisk, that will deliver such call to a remote and previously configured Asterisk gateway (VPN). - The 'remote' Asterisk should converts this call, speak to the PBX connected and finally the phone ring. * Phone -> Analog PBX -> Asterisk -> INTERNET -> Asterisk -> PBX -> Phone * Straight to the point: what kind of hardware I need? I saw some PCI cards (like Digium Wildcard TE110P) but I am not sure what to buy. Any help, URLs is very much appreciated. Thanks in advance, Giorgio Mandolfo

Without knowing what interfaces it has available, that's a difficult question to answer. If it's got an E1 or T1 interface, buy an appropriate port-density T1/E1 card (surprise) like a TE110P or TE410/405P. If it's analog, and appropritaely-configured TDM400P would be the way to go. Cards are cards....get what you need to make the interface happen. It's like asking what card you need to connect your computer to some undescribed network. If the network is ethernet, you need an ethernet card. If it's token ring, you need a token ring card, etc. Daryl
