This is a common issue with Canadian outbound. Branded calling isn’t widely available yet outside the US, and STIR/SHAKEN is limited in Canada. What does help in practice is improving call reputation and delivery: proper CNAM registration for Canada, warming up the number, reducing call bursts, using local area-code matching, rotating numbers, and adjusting call timing. Carrier filtering is very sensitive to volume and patterns. I’ve helped clients improve pickup rates in CA by tuning Twilio settings, call pacing, and carrier trust signals. Happy to take a look at your setup and suggest concrete fixes. @Ace K
