I see on the VFX hardware page the following is listed as a certified device.
I'm assuming that this is a just a typo and should be the WRTP54G-AU? i.e. with a P for Phone.
My boss phoned to get some vfx VOIP lines installed using a WRTP54G and was told that this was not a certified device and that he'd have to use Open-VFX. The WRTP54G was one of the first certified devices, I used to use one. Could it be that the WorldXChange staff are checking the website for the certified models and the typo is misleading them?
Anyone reading this thread, I've got a WRTP54G available that has been rock solid for a number of years. Just got a new model as present from a friendly guy, no other reason for upgrade. PM me if interested, else it will go on TradeMe in the next couple of weeks.
