Hello,

I am working with Skype4com last version. I have seen, in some cases, when can not be direct TCP communication between two Skypes it uses relay. In this cases I am communicating this skypes with app2app. When I send messages using write command, messages are delivered through the reley via TCP. I get around 1.5Kb of bandwidth. But when I send messages using SendDatagram command, messages are send via UDP through the reley.
In this enviroment I have done a video call and video packets are sent via UDP directly.

Is there anyway to send direct app2app message via UDP in this scenario?

I have seen I could send message when there is a call with CallChannel. is it work like app2app?

Thank you.

Fernando.
