We're a telecom company who uses Cisco AS5400 call gateways to route incoming ISDN calls to our Asterisk PBX servers on the same LAN. We need assistance configuring a Cisco AS5400 to:
1. Receive incoming ISDN calls (this part is already working as calls do hit the Cisco).
2. Pass the calls via SIP to our Asterisk PBX servers based on DID (this is not working).
3. Make general suggestions / improvements to our Cisco configuration.
We are running firmware version 12.3.
Please, only bid on this project if you've configured AS5400's before.
