1. A communication method comprising:
- transferring, using a first network switch, data packets associated with a first voice packet stream between a first secure network domain and a first codec while restricting other data packets not associated with the first voice packet stream, the first voice packet stream encapsulating an analog voice signal;
transferring, using an analog voice line, the analog voice signal between the first codec and a second codec; and
transferring, using a second network switch, data packets associated with a second voice packet stream between a second secure network domain and the second codec while restricting other data packets not associated with the second voice packet stream, the second voice packet stream encapsulating the analog voice signal, the first secure network domain classified according to a first security level that differs from a second security level of the second secure network domain.

Abstract
According to one embodiment, a communication network includes an analog voice bridge coupled to two secure network domains that each have a differing security level. The analog voice bridge includes two codecs that are coupled together through an analog voice line that transfers analog voice signals. The analog voice bridge is coupled to each secure network domain through a network switch that transfers data packet streams from their respective networks to the codecs while restricting data packets that are not associated with the data packet stream.
