  At the last few years, multimedia communication has been developed and
improved rapidly in order to enable users to communicate between each other
over the internet. Generally, multimedia communication consists of audio and
video communication. However, this research concentrates on audio conferencing
only. The audio translation between protocols is a very critical issue, because
it solves the communication problems between any two protocols. So, it enables
people around the world to talk with each other even they use different
protocols. In this research, a real time audio translation module between two
protocols has been done. These two protocols are: InterAsterisk eXchange
Protocol (IAX) and Real-Time Switching Control Protocol (RSW), which they are
widely used to provide two ways audio transfer feature. The solution here is to
provide inter-working between the two protocols which they have different media
transports, audio codecs, header formats and different transport protocols for
the audio transmission. This translation will help bridging the gap between the
two protocols by providing inter-working capability between the two audio
streams of IAX and RSW. Some related works have been done to provide
translation between IAX and RSW control signalling messages. But, this research
paper concentrates on the translation that depends on the media transfer. The
proposed translation module was tested and evaluated in different scenarios in
order to examine its performance. The obtained results showed that the
Real-Time Audio Translation Module produces lower rates of packet delay and
jitter than the acceptance values for each of the mentioned performance
metrics.
