Can I use both my answering maching and the SECV voicemail?

Yes.  You can have your calls answered by your answering machine as the first priorty.  If your machine does not pick up because of a power outage or you are already on the line, the calls will be answered by the SECV voicemail.  To do this log into the secv user portal at and under the call handling section, change the time on the no answer - send to voicemail selection to a greater time so that your answering machine has time to answer first.
