Well, I'm not an asterisk Guru but I'm fairly good with Cisco stuff... If you have a CCM (Callmanager), you also use a router as gateway. As the IP-phones wich are managed by the CCM DO display incoming caller-id, I suppose, the router is capable of relaying that information. However, the connection between the router and the CCM is usually realized with h.323. When you take those information and look at them logically, I think, you have quite a good chance that you will get your caller-ids. Either the router relays them via SIP or you take one of the h.323 channels for asterisk. Anyway, my question is, why don't you use a T1-card for your asterisk. I suppose, a T1-card from Digium is MUCH less expensive than a big Cisco with a Cisco T1-card...
