Hi Tarmo,

if you look closely, Diego is doing video.
To my knowledge there is no free H.323-SIP gateway that supports video.

Regarding the port negotiation:
The only way to change the ports is to close the logical channel and to
open a new one. (as we discussed on the Packetizer board)

In my case, I developed a H323-SIP gateway (that does not handle media, only signaling conversion) and the SIP side sent a reinvite with a different audio port, so I need to make the H323 device send media to this new port. How can I accomplish this? (both in terms of the H323 protocol itself and implementing the solution using H323Plus). I appreciate any help, thanks.
