Videotron exchange codes Here's a list of exchange codes for ex-Videotron numbers. Calls between numbers with these codes are unmetered off-peak and at weekends. However, calls between London and Southampton numbers are charged as per calls to BT numbers; the BT network is between the two CWC networks, so CWC must pay BT access charges which are a great bone of contention at the moment. If there are any corrections please contact me.
