Audio/Video Standards

[nello]

From a tandberg 6000mxp want to show peoples in conference and PC present. over a Tandberg2500 and AETHRA 8400. (ISDN) (BRI).
Using H.239 and G.728 protocols will the far end able to see peoples and presentation at the same time if they are using different protocols?
thanks.

H.239 doesn't change. G.728 is just an audio protocol. When the units connect they will decide what protocols they can use.

Why G.728 particularly? Are you using 128Kbps ISDN? Providing all endpoints support H.239 (so make sure you have the option keys etc), then this should be fine. From what you say, it looks like the 6000MXP is hosting a 3 way multisite conference, in which case, remember that the H.239 presentation will only work from the host system, i.e. the 6000MXP. Should either of the 2 remote sites send content, this may not display as a H.239 secondary video image.
