Virtual telephony services in Czech Republic

To receive calls, you will need to set up forwarding in your personal account (to SIP, mobile, Telegram). To set up outgoing calls, we have collected step-by-step instructions for setting up a SIP line in various applications and devices. A short procedure for setting up IP telephony is not difficult and will allow you to receive and make calls.

VAT is not included in the prices shown on the website. Since most of KataTelecom's customers are companies, they do not have to pay VAT and therefore we charge a fixed price as shown in the tariffs. VAT is still charged to individuals resident in the EU and can be applied to all fares. If you are doing business in the EU, please make sure you enter your VAT number to verify your business status and thus remove the addition of VAT to the price. If you are located outside the EU, we will not charge VAT, regardless of your business or status.
