[VOIPSEC] VoIP and Banking Security

[Al]

Greetings,

New here, and yes, I did check the archives first.

I just finished a session with my bank using the touch pad on my phone.
When finished I dumped the packets captured during the transaction (using
ethereal).  I was a little dismayed and a lot alarmed to see wherever the
protocol was RTP EVE that the numbers I pressed on the phone were visible in
the info field:

     Payload type=RTP Event, DTMF Eight 8

I'm guessing that if I can sniff these packets, so can anyone else.

Anyone have any comments to calm my nerves?

Thanks,

Al
