Consider this topology:
IP Phone-->Cisco CallManager--H.323-->2851--T1CAS-->MX/Alliance Turret System
The MX/Alliance T1 is configured for Foreign Exchange Station (FXS) loopstart and Super Frame (SF)/Alternate Mark Inversion (AMI). When the T1 controller on the Cisco 2851 Integrated Services Router is configured for Foreign Exchange Office (FXO) loopstart and SF/AMI, calls from the IP phone to the turret work fine. But the 2851 never sees an incoming seizure from the MX/Alliance due to non-standard signaling used by the MX/Alliance.
The solution is to insert an RAD Vmux 2100 Circuit Emulator/Transport Device between the Cisco IOS Gateway T1 Controller and the MX/Alliance Turret System. Because the Vmux 2100 converts time-division multiplex (TDM)-to-IP and back to TDM, the Cisco IOS Gateway T1 Controller can be configured for E&M Immediate-Start, ESF/B8Zs while the MZ/Alliance remains configured as T1 FXS loopstart, SF/AMI.
Complete these steps:
Connect the Vmux 2100 to the Cisco IOS Gateway T1 Controller and the MX/Alliance Turret System according to the instructions provided by the manufacturer.
Configure the Cisco IOS Gateway using the steps outlined in Private Line Automatic Ringdown for Trading Turrets.
