I haven't been able to test this yet since I don't have another line handy that offers the name display ability, but it should work with any number that attaches the name along with the phone number.
From past experience, Rogers Wireless and most land-line providers will attach the subscribers name to an outgoing call unless specifically turned off, so any incoming calls originating from those networks should show up and presumably those of TELUS/Koodo/Public Mobile subscribers if the subscriber name on the account is attached when making an outgoing call. I'm interested to see if that's the case, or if it only works inbound on our lines at this point.
Update: I had someone call me from their landline and sure enough, the name was displayed along with the phone number. I also had a friend on Koodo call me and it only shows their phone number, and the same thing when I tried calling them.
So it looks like name display works on an incoming basis with with providers who are attaching the name information (also known as CNAM) with the outgoing call information such as Rogers and landline providers as mentioned earlier, but there's no outgoing call display being sent from TELUS/Koodo/Public Mobile at this time.
