...the issue I have is that the number is saying it's a long distance call, but both the landline and my 825 number are both based in Edmonton.
Actually the message states it may be a long distance call -- since the same system is shared by Telus, Koodo, and Public Mobile, the switch doesn't know your plan so it states a generic message heard by all subscribers. But all current Public Mobile plans include Canada Wide long distance so nothing to worry about.
That message seems somewhat common of some prefixes actually... I also randomly get the warning for a local Regina prefix.. I know it's an Iristel prefix common with VoIP providers including Microsoft's Teams. The call will still complete after the warning, but just prefix with a 1 to guarantee never hearing it.
