Call costs VoIP telephony

Although many business owners think that with IP telephony you call for free, however, this is not true. Even if you call through your Internet line, you still have to pay call charges when you call landline or mobile numbers.

The good news, however, is that these call charges are easily up to 60% cheaper than making calls over ISDN lines. International calls themselves are easily up to 80% cheaper.

  • National calls: up to 60% cheaper
  • International calling: up to 80% cheaper

Cost of ISDN lines

A big savings also comes from completely eliminating your costs for ISDN or BA lines. Currently, you pay between €22 and €40 for 2 simultaneous calls. These charges will disappear completely!

So if you currently have 4 simultaneous calls you easily pay up to €80 in ISDN subscription fees. So when switching to VoIP telephony , you are already saving €1,000 on an annual basis.

  • Charges for ISDN or BA lines disappear
  • No additional charges for telephony connection

Summary savings VoIP

Concretely, you save up to 60% on your call costs and the monthly subscription charges for the ISDN lines are eliminated. You can easily find these costs on your current Proximus or Telenet phone bill.

On average, Belgian companies save between €800 to €5,000 annually when switching to VoIP telephony.
