When data is replayed by the server the receivers of this data observe that all packets come from one host. Many media tools have been designed to expect that each source comes from a different host. If multiple sources for each media are being replayed then all the sources seem to be one host, which can confuse some media tools. As there are some mechanisms available to overcome this problem other media tools are more tolerant.
There are currently two known approaches to this problem:
For problem free source identification on replay media tools need to be designed with media recording and playback in mind. Using RTP is a good approach for this as it allows host independent channel identification, however not all media tools are compliant with this mechanism.
