[Asterisk-Users] frames/packet

[Steve Underwood]

That is not just true of IAX. There appears to be substantial amount of 
RTP traffic, which trunks a variable bundle of calls between the same 
two points, used by IDD services. The traffic has to be going between 
the same two points to make that work, though, whichever protocol you 
use as the transport.

Steve
