Call-Blaster is a powerful call distribution system which rings a set of phones at the same time. The first phone to answer gets the call.

This low cost service allows any Flextel customer to ring 8 destinations and the service is ideal for busy individuals or business that would like to ring a group of phones simultaneously.

Also known as a Call Blasting Group, the target phones in the group to be blasted can be landlines, mobiles or even Internet based soft-phones based anywhere in the world. Once setup all the phone numbers that have been entered into the blast group will be rung at the same time, the first phone to answer will get the call.

The service is particularly well suited to small teams providing sales, support, service or helpdesk functions. It can also be used for emergency callout, ringing the whole set of numbers until someone answers, this could be configured easily and quickly and would allow peace of mind for an elderly relative or any vulnerable person. An ideal application is where a team is spread over a wide area on mobiles or phones. A powerful solution for dealing with mobile network coverage issues.

As there is no charge for linking Flextel numbers of the same code together, you can easily combine Auto-Attendant, Hunt Group, Call-Blast or Diary Rerouting features to build a powerful solution, tailored to your needs.

For example a user can easily setup a series of hunt group destinations, those destinations all having an associated blasting group of upto 8 numbers. i.e. permitting first team call out, then if no answer, backup team call-out. The complexity is up to you and your specific needs. See our Solutions section for more ideas.

  1. Activation - after logging in, set the Destination of your Flextel number to Call-Blast mode, using the drop down menu.
  2. Setup your Extensions - just click Extensions and then add your Extension Phone numbers and Label them for easy of use.
  3. Setup your Handsets - Call Blast can only work reliably if the target phones have been set with 'all diversions cancelled'. If diversion is left active e.g. to voicemail and the mobile is turned off, busy or out of signal then, our system receives an answered call signal and the 'blast' is completed.

    You may be able to cancel diversions from your handset or your Service Provider's online portal. If not, then call your Service Provider's support line and request that they disable the diversion to voicemail; you'll be able to set ICD on your Flextel number to voicemail, if you do want the option to go to voicemail eventually.


  • Divert on no-reply Select the time for the extensions to ring, we suggest 20 seconds if you use mobile or international extension numbers. Any longer and the mobile voicemail (if left active) might answer and disrupt your call management design. Any shorter and the mobile may not ring, due to call setup delays of well over 10 seconds, in some congested mobile networks.
  • Voice Mail You can record you own announcement to find out how see our Voicemail feature. If you do not want callers to leave a message you can Deactivate it using the dropdown or select an alternative destination to try e.g. your own voicemail system or a call answering/receptionist service.
  • Screen Anonymous Callers - just check the Anonymous box. Now any caller that withholds their number will be diverted to the Divert(ICD) destination (normally Voicemail)
