The IPS: 724 number will be my voicemail number. The voicemail number will direct callers directly to my IPS: 412’s voicemail box. This means just one voicemail box to check instead of two. While I won’t know which number they would have called, I will still get the important voicemail. Not only can I listen to the voicemail by dialing the voicemail access number, but I will also see the voicemail on my web portal, and will have it email?ed to me.
