RTP Player

Hi,

Your email provider still does that, and I don't like it.

If you look carefully at your trace you'll see several things.
1. The codec used for voice is G723. Wireshark doesn't natively support that.
The RTP player doesn't handle that gracefully though.
2. There are RTP events in there, which represent inband signaling of call
control. These confuse the RTP analyses somewhat as well.

You better have a look at Statistics|RTP streams if you want accurate details
on the media. The RTP player can only give you an *impression* of what it
sounds like, and then only if the applicable codec is available.

Thanx,
Jaap
