Indeed, you and hwstar are quite right on this one. I had forgotten about
the udp issue. My clients have asked me on occasion what sort of security
there is for voip conversations so I look forward to encryption in IAX.
It's usually not a big deal though because they realize their normal
analog voice conversations aren't encrypted either so it will be another
point in favor of VOIP when encryption is standard.
