I want to pilot a VoIP setup in our office using an Asterisk box. Can someone tell me if there is a desktop phone that is capable of VoIP service and analog service from our office phone system ? This would be a solution to having two phones on the desk. I could make and receive calls on either the VoIP system or the regular office phone system on the same phone. It would also allow me some sort of fail-over in the event that the internet was down for some reason. we could still make and receive calls on the system. I realize that we can terminate the analog lines into a card on the asterisk server, but just for initial trials and perhaps future uses I would like to see if there is a phone that is capable. Thanks.
