Has anyone been successful with converting an H323 9608 to a SIP device? I have an Avaya SBC that we are testing and have Avaya communicator, One X Mobile SIP and SIP trunking working through it. I'd like to be able to get some IP phones to register, but the SBC we have only supports SIP not H323. I am also wondering if functionality is lost vs H323? I have a customer that wants to put single phones at each one of there small locations across the US, and was hoping o use public authentication through the SBC to obtain this
