Using VoIP for POTS Voicemail with an OBi110


Those of you who mix VoIP and POTS may find it useful to use VoIP-based voicemail when you're unable to answer your POTS calls.  There are a few reasons you might want to do this.  VoIP voicemail is typically free, but POTS providers often charge for it.  VoIP voicemail often has more/better features, such as email or SMS notification, or even multiple voicemail boxes for different people.  Also, it might be convenient to have one single mailbox to check instead of having to check both a POTS mailbox and a VoIP mailbox.


In order to accomplish this, you will need an OBi110 with a Service Provider configured for SIP, and a SIP URI or extension number that is routed to your voicemail.

Set up your OBi110 as follows.  This assumes SP1 is configured for SIP, and your voicemail extension number is 1001.

Physical Interfaces >> LINE Port:
Calling Features >> CallForwardOnBusyEnable: (checked)
Calling Features >> CallForwardOnBusyNumber: sp1(1001)
Calling Features >> CallForwardOnNoAnswerEnable: (checked)
Calling Features >> CallForwardOnNoAnswerNumber: sp1(1001)
Calling Features >> CallForwardOnNoAnswerRingCount: (up to you)

If you want your VoIP provider to receive the caller's Caller ID, also set the following:

Service Providers >> ITSP Profile A >> SIP:
X_SpoofCallerID: (checked)

Now, voicemail is ready for your use.
