If a phone number dials your own number, there would be two legs. The first leg is the inbound leg, which is the call from the caller to the virtual phone number. The second leg is the outbound leg, which is the call from the virtual phone number to your own number. If the phone number does not call any other number, for example terminating to Voicemail, then there would only be one leg for that call.
Does a call have more than one leg?
