Abstract

In a communication device operable in at least two states, a method of transitioning between a call in a first state and a second state, each state having an associated number, each number having a prefix portion and a suffix portion, the call having at least one called party and a calling party is claimed. A party requests a change of state. The called party sends at least the suffix portion of the number corresponding to the second state to the calling party. The calling party compares the number corresponding to the first state with the number corresponding to the second state. The calling party appends the prefix portion of the number corresponding of the first state with the suffix portion of the number corresponding to the second state, and establishes a new call using the number corresponding to the second state.
