Sorry to bring back an old thread, but I have a related question to the one above. Not an important question, just something I wondered about
When a ported number is called, what exactly happens?
If, for example, a BT landline was used to call an O2 number that had been ported to 3, would BTs exchange/switch first try connecting to O2, then O2 would divert the call over to 3?
Or would the BT switch have a comprehensive list of all numbers that had been transferred to other networks?
Similarly, how are text messages sent to a ported number dealt with?
