no dialtone on MICA after IOS upgrade

I upgraded my 3640's IOS to 12.4.12 and in the process I erased everything in the flash. After uploading the new IOS I put mica-modem-pw.2.9.5.0.bin on the flash. It is the same mica software that was on the router before. Now after I reloaded the router all routing functions are fine but I get no dialtone from the MICA when I try to call out.
