Does your analog PBX have trunk lines? Does it support a PRI? You can just use any voice gateway like a 2811 with FXO or a T1 card for the PRI. If you give us more details we can give you a better idea of what you need.
I have a similar scenario in my office. I have CCM at main location and PBX at the branch office. I am using Cisco ATA 186. ATA186 has two FXS ports on it. I connected both the ports to the trunk card of analogue PBX. Connect the ATA in the network and assign it the Call Manager to use. This will cause the ATA to register its both ports on the CCM (if auto registration enabled). Assign the DN and thats it .. :)
