When you are using ip and h.323 to place a video call from one company to another over the public internet do you need to convert the call back to voice or is it ip all the way through?

    Yes, as Labnuke99 said, it is IP all the way through. I would like to provide few more info on the same. H.323 is one of the VoIP protocol which is based on packet-IP network. So, whatever packet comes it will be flowing through IP (internet). H.323 uses additional protocols called H.225 and H.245. H.225 is used for call signaling i.e. initial call setup/ringing/connection (here in video conferencing - finding the neighbor contact and make a connection). Once the connection is done the H.245 control signal protocol shares the media details about the audio/video codec details and starts the video/voice flow using RTP (Real-Time transport protocol). So there is no need of any converters in between. Thanks!!!
