What I've got:

ISP->Switch->Microwave T1 <-> Microwave T1->Switch->Static IP xx.xx.xx.8 (VOIP device)

What I'd like to do (if possible):

ISP->Switch->Microwave T1 <----> Microwave T1->Switch---> (1)
|------> (2)
(1)->Static IP xx.xx.xx.8 (VOIP device)
(2)->Cisco 2600 FastEthernet 0/0 -> Serial 0/0 -> Microwave2 T1 <--> Microwave2 T1->Cisco 2600 Serial 0/0 -> FastEthernet 0/0 -> Static IP xx.xx.xx.4 (VOIP device)

The two VOIP devices are on the same IP subnet and are route-able IP's.

If I understand things, the FastEthernets need to be route-able IP's. The two Serial ports can be non-route-able.

I have connected devices through 2 2600's using the following, but can't wrap my mind around how to do what I want w/o having more than the two static IP's xx.xx.xx.8 and xx.xx.xx.4:
Current configuration : 695 bytes

service timestamps log uptime

!
end

Any help is appreciated.
