3CX SIP Trunk Providers – Canada

These SIP Trunk providers in Canada have been tested and certified by 3CX. We strongly recommend using a preferred or supported SIP Trunk service provider. The 3CX team makes sure that all templates from listed SIP Trunk Providers are updated and tested with every release ensuring no issues arise for our users.

Registration-based trunks with no IP fixation remain the preferred option in a hosted environment. This is because in certain cases the Public IP of your Hosted by 3CX can change unexpectedly. Although this is not a regular occurrence, if this happens, you will temporarily lose the ability to make and receive calls via your IP-based trunks.

Read our guide on how to configure a SIP Trunk / VoIP Provider. This covers the generic steps required to configure a trunk with 3CX. Some providers may need special configuration requirements. Before choosing a SIP Trunk provider in your region, carefully check our listing for these special requirements and be sure to follow any extra configuration guides added.

Preferred Providers are compatible with all 3CX installation modes. They are thoroughly tested with each build of 3CX and require no manual configuration. You can simply plug and play your PBX with a SIP Trunk of your choice.

Supported Providers (Dedicated Servers only) are tested against 3CX Hosted and on-premise installations. Not compatible with 3CX FREE/SMB. Configuration may require a few extra steps.
