The advanced call forwarding feature gives you the option to route your incoming calls to up to four different phone numbers (other than your main VoIP number) simultaneously and/or sequentially so you can answer the call wherever you may happen to be.

Any phone can be used as a destination - your home phone, another VoIP phone, your mobile phone, even a PDA or computer with a Softphone, regardless of where the device is located.

Examples of different CallBlast call forwarding setups

  • Simultaneous,

- are on the CallBlast tab, as shown below.>

CallBlast Tab for Advanced Call Forwarding

The above CallBlast call forwarding configuration would work like this:

  1. Ring the Primary VoIP line of 5039141300, which is on D01L01 (the first line on the first device) for 6 rings before going to voicemail.
  2. If the Primary line hasn't been answered after one ring, begin ringing 5039141310, and ring that for 4 rings before stopping.
  3. If neither phone has picked up after two rings, begin ringing 3108614708 and ring that for 3 rings before stopping.
  4. Warning: if any of your CallBlast phones has voicemail that picks up before the call is answered or goes to VoIP voicemail, your voicemails will all be on that other phone's messaging system! In addition, if the total of Rings Delay plus # of Rings on any of the CallBlasted phones is greater than that same total for your Primary VoIP phone, the call will be handed off to the Phone with the longest total, and thus will not go to your VoIP Voicemail.
    This means, for example, if your mobile phone is set to 0 rings and you have it turned off, many of your calls may go to your mobile phone voicemail. Or if your mobile phone Rings Delay and # of Rings totals 8 in the example above, then an unanswered incoming call will simply die instead of going to your Primary VoIP voicemail, since that only totaled 6 rings. If you set Rings Delay to 2 for your mobile phone, which will mean that your VoIP phone will ring roughly 3 times before your mobile phone begins to ring since it takes 1-2 rings on your VoIP for a CallBlasted phone to begin ringing even if you have Rings Delay set to 0. And make sure that your mobile phone will stop ringing at least 2 rings before your VoIP phone sends the call to voicemail.

    CallBlast Call Forwarding to IP Phones

    To include an IP phone as one of your CallBlast call forwarding numbers, enter the IP Device ID, which is usually in the form of a URI. A SIP URI is the ID and network address of the IP phone and may bear no resemblance to a "normal" telephone number.

    To Set up CallBlast Advanced Call Forwarding

    • Enter your mobile, home or other numbers in the Phone 1 thru Phone 4 fields as shown.
    • You make the number active by checking the Active checkbox, or take it out of CallBlast call forwarding by unchecking the box. If you want calls to go directly to voicemail, you can either turn on the DND feature by pressing *78 on your phone, or you can enter 0 for the number of rings on your Primary VoIP phone, or you can make your Primary VoIP phone not active. You can also enable the DND feature by clicking the Features tab and selecting the DND checkbox.
    • You can Disable Call Waiting on that particular device by checking the next box associated with that number.
    • Next, set the Rings Delay, which is the number of rings on your Primary VoIP line that CallBlast call forwarding waits before launching a call to the CallBlasted number(s). Zero is recommended for your Primary VoIP phone.

      Note: It takes 1-2 rings for a mobile phone to begin ringing even if you have the Rings Delay set to 0.

    • Last, set the # of Rings for each device, after which the CallBlast call to that device will be stopped. When a call is answered on any of the devices, CallBlast call forwarding automatically stops ringing all other numbers. If the call is still unanswered after the # of Rings for the Primary VoIP line, the call is delivered to your VoIP voicemail.
    • Click on the Update CallBlast button to save all changes.
    • Make a test call to your VoIP number to make sure it works as expected.

      Note: If your mobile phone is a CallBlast number and you turn off the mobile phone, all your calls will go to your mobile phone's voicemail. Also, if you immediately push the Ignore Call button on your mobile, the call goes to the mobile's voicemail and not the primary VoIP voicemail.

    CallBlast call forwarding Configuration Examples

    The CallBlast tab provides five different sample CallBlast call forwarding configurations. Look on the left side of the CallBlast screen and click on the button for the type of setup you want. A pop-up window appears and describes the configuration and its results.

  • "I use SIPTalk for both my home office voice line and for my fax machine, and it works much better than my previous VoIP provider did. My fax machine is my business lifeline, so I can’t afford to use an unreliable service. In addition, I save about 50% over what I would be paying AT&T for the same two lines. "
