An apparatus and method of establishing a communication connection is provided. A one-way delay is not approximated by an average of a two-way delay calculation. Instead, a first time difference is determined based on a round-trip delay of a transmission over a packetized network and a circuit-switched network. A second time difference is also determined based on a round-trip delay of a transmission over the circuit-switched network. Then a delay value is calculated based on the two time differences.
