I dont think that you can do that why_? because the ip devices may have something like a macaddress and wen your ISP or other and depending on your service i mean that if you only have the service for one device the second device wont work due to devices ID or macaddress. in that case you need a router.

and about sharing a cross over cable, i dont now if i understand this, some hubs dont need the cross over any more unless you conect several hubs in cascade, but in example a cross over cable is tipically use for connecting 2 PC's directly to one and other. if you want to connect them with a hub you dont need a cross over cable.

it depends on your hub, if your hub requieres a cross over cable then your answer is yes, the cross over cable is some times use in this devices to connect the cable modem to the hub using the cross over cable.

hope it works for you.

If I'm understanding the question correctly, the answer would be no.

Cable modem, like DSL service, generally comes in two flavors: PPPoE (PPP over Ethernet) or MAC-address secured. So, either your provider requires your PC or your router to establish a PPPoE session (with username/password) or it has a record of your one allowable device's MAC address.

Your two VoIP boxes would have different MAC addresses, so that wouldn't fly. You would only be permitted to use one PPPoE session, so that would keep at least one of your VoIP boxes locked out as well.

Prior answer would be correct: you need a router in between your VoIP boxen and your cable modem device. The router would present a single MAC address and a single PPPoE session (if required), and the VoIP boxes would share that connection.

You would have to buy a second ip address for the second box.

Or put a voip friendly router on the modem.
