I have a MICS 4.1 with PRI and a 4 port LS/DS trunk module. I have the 2 trunk ports connected to a cisco 1750 router with an FXS card. When a call comes in from another location the trunk card rings twice before pocking up and giving dial tone. All else works fine after I get the dial tone. I would like the auto answer to pock up right away like the pri, I know this should be happening but it is not. The only thing I can think of is that the FXS card is not sending Disconnect supervision signal, however in this case should it not ring the prime set than(it is not).
