I have and ACS R1.1 with Voice Mail R4. The Voice mail started giving me trouble with intermittent garbled messages. I replaced it with a R5 mail. The messages are now clear, but now we cannot retrieve all of our messages. When we press 0 to retrieve the mail, the Voice message comes back with you have X number of messages. It will not let us listen to our messages. This is intermittent. Sometimes we can answer all and sometimes we cannot. This is on all extensions.
Could I have a defective Voice Mail Card are is R5 not compatible with ACS R1.1.
