Our Road Warrior Encrypted Obi Setup

<< < (2/2)

I'm a VPN novice, but I defined a PPTP VPN connection between my laptop and my home DD-WRT router.

I think connecting the OBI to the Laptop using the bridge function would get a secure voice connection.

I see no reason why that setup wouldn't work assuming you have enough up/downstream bandwidth at home.  The tunnel should make it all secure between the two.  With additional complexity there might be a little lag but I'm sure it would be acceptable. 

rob613:
Does using the 9-digit Obi number require enough data outside of the VPN create a risk?

But more significantly, what do you gain over a SIP softphone on the laptop or whatever modern equivalent of a Yap-phone - phone handset on USB cord?

And if going that route don't you get the opportunity to make a SIP to SIP call or use a directory only within a VPN-protected server?

If you are registering your SIP phone to a SIP-to-GV gateway you still get outbound dialing by GV, and just by registering the SIP phone to any SIP server you can get a PSTN line that GV can ring to and then call out from the GV web interface.   I don't think there is any problem doing this while traveling.

To stick with a hardware phone port, did you consider building one into the hardware firewall?     Or comparing exposure of unencrypted data using other hardware devices that bring out a phone port from a small device hanging off USB or Ethernet?
