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 the 3CX VoIP solution. These providers have pledged to support 3CX by providing you with a template to ensure interoperability. This means 3CX is able to remain one of the best VoIP PBX vendors on the market. It should be noted that these 3rd-party providers have not undergone an interoperability test by 3CX and we can not support you in the case of any issues with your phone service.

If you are a SIP Trunk provider and wish to become a 3CX Certified Interop Partner apply here.
