I was told or thought you could do the setup? IP500 with SBC (Portwell). IPO is R10.1 and SBC is 7.1 How can i get a Avaya 9608 to register over the WAN through the SBC to the IPO? I have done remote worker installs including onex mobile for IPO but can i load SIP software on the 9608 and point it to the B1 interface of the SBC and get it to work?
