3CX Supported VoIP Providers

SIP Trunks / VoIP Providers are a convenient way to connect 3CX to the PSTN. 3CX supports leading VoIP providers across the globe. These VoIP Providers have been tested with 3CX, and pre-configured templates are included in the phone system that makes configuration easy and quick. Furthermore, both the VoIP provider and 3CX have committed to fully supporting the combined solution.

We strongly recommend using a supported VoIP provider with 3CX. The 3CX team makes sure that all listed VoIP Providers’ templates are updated and tested with every release ensuring no issues arise for our users. Select your country to view a list of supported SIP trunk providers in your country.

Alternatively, there are also a number of 3rd-party supported SIP trunk providers (uncertified) which can be found here along with information on how to add their template to 3CX. These providers have pledged support for 3CX and can provide you with a template. It should be noted that these providers have not undergone an interoperability test by 3CX and we can not support you in the case of any issues. If you are a SIP Trunk Provider and wish to become a 3CX Certified Interop Partner apply here. For more information on what SIP trunking is, the benefits and advice on how to choose the right SIP trunk provider for you, visit our SIP Trunking Explained page.
