I work from home so one is from work and the other is my wife/family Ojo.
Re: Firewall: You don't need to do that since SIP connections are very flexible. In fact, if I remember correctly, you can, theoretically, plug in up to 75 ojo's behind one IP address where as the H323 protocol limits you to one VP per IP address.
I'm not a techie and I don't pretend to be one but this definitely is a big PLUS for the Ojo in terms of having multiple units in a home/office without having to request additional IP addresses.
Cool, thanks for explaining. I thought SIP-based devices were flexible, but not THAT flexible. My wife ordered an Ojo for herself, so I'm looking forward to having two Ojos on one network.
