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 eight (8) target 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 softphones 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 help desk 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.

Sometimes, calls may be answered by an 'Extension's' network; possibly voicemail or out of signal message, which will disrupt the call. Our Call Screening feature will overcome this for you as it requires an action by one of the extensions to 'Accept' the call.

Text Blasting is available as part of Call Blasting, if you are using a Flextel Virtual Mobile SIM. It lets you forward any text received by the Virtual SIM to each UK mobile in the blast group.

To ensure an accurate log of all messages received, a copy of the text can also be emailed to any email address.

Virtual SIMs are available in the Shop.

Text Blasting is charged at our standard text rate. You pay one text charge for each text sent to any UK mobile in the Call-Blast Extensions.

In the Number Settings page you have the following controls...

  1. Activation - set the Destination of your Flextel number to Call-Blast mode, using the drop down menu.
  2. Setup your Extensions - now click the Extensions Button 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 ALL the target phones have been set with "all diversions cancelled".

    If diversion is left active on just one phone in the Blast Group (e.g. to voicemail and the mobile is turned off, busy or out of signal) then our system will receive an answer and the 'blast' is completed, so ringing is stopped on all the other phones or mobiles. This could mean other users in the Blast Group do not get a chance to answer the call.

    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.

In the Number Settings page you have the following advanced controls...

  • Timeout on no-reply Select the time for the extensions to ring, we suggest 20 seconds, especially, 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.
  • Voicemail You can upload your own high quality 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)
  • Call Screening - check the Call Screening box. Now you have to press key one on your handset to accept the call. This stops calls accidentally routing to a voicemail service, as it requires a positive action by the called person to accept the call.
  • Text Blasting options - If you want to use Text Blasting and are using a Flextel Mobile Number, then by using the SMS dropdown menu, you can choose to forward text messages to:
      • Phone only,
      • Email only or
      • Phone & Email.

    So in the case of Blasting, then any UK Mobiles in the Blast Group will receive the forwarded text message, if Phone only or Phone & Email are selected. Remember that each SMS text message sent is chargeable.
