124 / Forwarding your calls
Be careful to avoid redirection loops. If for example, you redirect your lines
to your branch office and your branch office redirects its lines to you, you
can create a redirection loop. If these calls are long distance, you end up
paying charges.
In certain situations, callers may experience lower volume levels when you
redirect calls to an external location.
