Is support for SIM-based authentication mandatory in Number Verification v2.0.0?

Number Verification 2.0.0 has introduced SIM-Based authentication.

Is support for SIM-based authentication mandatory for all implementations? If not, how can API consumers determine whether this feature is supported?

Hi @trehman-gsma, the only difference between number-verification v1 and v2 is the SIM-based authentication. So one option could be to require SIM-based authentication implemented for v2, otherwise v1 should be used. But that's just my personal view, @camaraproject/number-verification_maintainers should add here.

If SIM-based authentication is not available with v2, and the fallback (network-based authentication) is also not possible, 403 response with code: NUMBER_VERIFICATION.USER_NOT_AUTHENTICATED_BY_MOBILE_NETWORK will be returned.

To provide the information upfront if SIM-based authentication is supported, maybe a service management functionality like https://github.com/camaraproject/CapabilitiesAndRuntimeRestrictions is needed.
