What is SIP Trunk?

SIP is the acronym for Session Initiation Protocol. SIP Trunking is the popular method being used for VOIP (Voice over Internet Protocol) calls. SIP Trunks creates, manages, modifies and terminates sessions with different parties in an IP network. Example of uses includes regular calls and larger conference calls with two or more connected participants. You can use SIP Trunk for:



  • Voice

  • Text

  • Streaming

  • Web conferencing

  • Screen Sharing




SIP trunks let you connect several channels virtually without the need for analogue phone lines. Thereby you can easily make calls over the internet, regardless of geographical distance. As a SIP Trunk provider, we can connect to your on-premise PBX (Private Business Exchange) system, which lets you establish contact without restrictions.

How our SIP Trunk technology works

Our SIP Trunk service is based on an IP connection between enterprise IP-PBXs and China Telecom (Europe)’s global network. Customers simply dial “a prefix number and phone number” to contact colleagues of branch offices or clients worldwide. No matter what fixed-network telecom operator you are using, you can purchase the service that requires no change on your end.



Our SIP Trunking solutions offer unique benefits for multiple types of organisations. For our multinational enterprise customers, our global VoIP solution offers valuable service based on our IP/VPN products. Our enterprise customers can make calls internationally to more than 70 countries across the globe via the VoIP of the PBX system.
