Default Voip Man In The Middle question.
In the last days the quality of my voip calls was non very good. I sniffed the ethernet stream with ethereal and I discover that the codec that I'm using is gsm06.10.
The problem is that the person that I was calling has a Siemens C450 Ip and it doesn't support GSM Codec!!!!!
What do you think? There is a Man In The Middle ?????

Default Re: Voip Man In The Middle question.
Assuming Ethereal reported the correct codec, something upstream was transcoding the session.

How were you making the call? Was there a provider in between or was it a direct phone to phone call?
