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.
