i knew it. i'll have to get my digital structures book out and build a flip/flop switch to take care of that. 

call flow. yes. here it is. get ready. don't blink. 

farmer's fingers -> analog set -> VG224 (SCCP) port -> campus cloud -> 3945 PRI (MGCP) -> PSTN -> Bank's IVR 

interesting part about the IVR reading back the numbers. i'll have to check that out.

obviously the F's are a problem. we can set them all to zeros with a 
9-volt battery and some copper wire. pop the cover off that bad boy 
and we'll get started. 

Are you going to tell us about the call flow? =) how does the call 
egress your network to get to the IVR?
