I think, though I am not for sure, that he is asking how to route a call 
from Asterisk to the Cisco device that is acting as the gateway (i.e. the 
E1 is connected to the Cisco and will only be speaking SIP to Asterisk). 

We had a similar setup before we replaced the Cisco with Digium Gateways. 
Basically we just set up a peer in asterisk with the IP address of the 
Cisco and routed external calls to it. The Cisco then actually placed the 
calls to the PSTN. Pretty painless, though sometimes a bit confusing to 
remember that if there were issues, you might have to check dialing rules 
in both Asterisk and in the Cisco.
