Excellent thought!

VOIPo may need the occasional ticket to open a new overlay, but otherwise that sounds effective. It would mostly be a bit of work and debugging as it is newly implemented. In routing, along with "unknown", they could add a separate rule called "Invalid CID". Require the NPA-NXX to be valid.

My In-laws who live in Canada had their call rejected the other day. I was wondering what was going on! I reject all but a few local exchanges. I do not have 416*******, but their 519******* is good to ring the phone.

On checking, their number was ID'd as 416825**** and should have been 519825****. Apparently this was a side-effect of a calling card service. I added my own *8251234 rule to let their specific 7 digit number ring in the future!
