RE: VoIP over IPsec

So do you suppose that in my scenario, I'd be better off leaving the VoIP out of the encrypted tunnels and use a separate [cleartext] path for them?

I'm worried about the security implications, not because I feel there is a huge security risk but because I'm sure the topic will be brought up. (Communicating over one provider's backbone provides little opportunity for third parties to snoop packets between points, of course.)

Has the issue of VoIP security ever been addressed? I suppose I should really do my homework.
