Free telephone system (PBX) for business customers

In order to offer optimal customer service and minimize costs, all companies need a telephone system (PBX).

Historically, PBXs have been complicated and expensive to operate. Switching to hosted systems has only made it a bit less complicated and slightly cheaper.

Redspot has for a long time wanted to be able to offer free PBX facilities that are also easy to use and are now the first to offer it.

  • No License Expenses
  • No hosting expenses
  • No subscription
  • No required service agreements
  • No hassle with maintenance

And this is not a limited time "free demo" as others offer it, a heavily limited feature version or an introductory offer.

No creative fees and more transparency, save 45-75 % on your calls

Not long ago, Redspot was the first to completely remove the call setup fee, which makes up up to 40 % of the phone bill. In addition, Redspot has launched a pricing calculator that makes it easy and transparent to see how much influence setup fees, billing per. minute, billing of call attempts and other creative settlement methods actually have on your telephone bill.
