I have a customer that wants Record-A-Call on his Partner Mail VS R5. The ACS is an R5. I've installed a 4-port card but it is the R4 4-port card (4X20 upgrade). I get all 4 ports to answer. However, when I push the record a call button, after about 4 seconds, the partner lady comes on and says 'record a call is now turned off and the alternating light goes off too. Any thoughts?
