WTG SIP TRUNK

The change from ISDN-based to VoIP telephony is a veritable step forward into the digital future. As a SIP TRUNK provider, we would like to take that step with you, providing you with the support you need as a service partner, product specialist and telephony service provider.

Our product, WTG SIP TRUNK, based on IP technology (SIP telephony), acts as the connection between your telecommunications system and the public telephone network. As a telephone interface, it bundles various telephone lines together and enables parallel telephone calls to be made via the internet. With WTG SIP TRUNK, you still have all the familiar functions of ISDN telephony at your disposal, but you also benefit from the added functionality of IP telephony.

  • Our knowledge is your added value

Call using digital telephony – flexible and secure!

WTG SIP TRUNK replaces your ISDN-based telephone connection. All outgoing and incoming, national and international voice and fax connections are switched and transmitted between your telephone system and WTG as your VoIP telephone service provider (using SIP telephony). The voice data is encrypted to provide you with the security you need in your communication. 

You can use a variety of solutions to insert WTG SIP TRUNK in your IT environment. To follow, we provide a short explanation of the three most popular installation options, whose purpose is to help you understand how SIP TRUNK works. You can find more detailed information on the product description.


Everything you need from a single source.

As well as SIP TRUNK, any optimally designed telephony solution will need a few other components. When switching from ISDN to IP technology, you need to make sure that such components as a Session Border Controller, a secure gateway, a carrier line with sufficient capacity and telephone system compatible with the new technology are in place – and that you are using the right telephone service provider. We offer you a comprehensive solution especially designed to meet your needs.
