I have an unlimited call plan with Koodo.
I have set up my comwave phone numbers to be redirected to my iphone 7 plus. I have a 1-866 and a 604 number redirected
I have been noticing when I get long distance phone calls from my redirected numbers ( I am assuming these are redirected calls, as all other direct calls work fine), my iphone just rings once and the call is terminated.
yet when I do a test call from my new landline to my redirected numbers my iphone rings correctly.
