Address the two most common objections truthfully (researched against CRTC,
FCC 2025 Third-Party Authentication Order, and STIR/SHAKEN cross-border docs):
- US-based long-distance termination operators routinely accept traffic from
Canadian carriers (cross-border voice is a standard interconnect).
- STIR/SHAKEN: a Canadian reseller cannot get a US SPC token (US-carrier-only),
so US-bound calls are signed by the upstream US-number provider that assigns
the DIDs -- exactly how most small US carriers already rely on upstream
signing. Canadian-origin traffic falls under the lighter CRTC regime, handled
by the upstream Canadian carrier. Does NOT claim S/S disappears -- it moves to
the upstream, off the carrier's day-to-day operation.
