With Vodafone having bought Worldxchange I'm wondering if my XNET/VFX line will eventually be able to use the VOIP Port on Vodafone's HG659 router and be fully supported by XNET/VFX?

At present I have a WRP400 running XNET/VFX plugged into a HG659 LAN Port which is a fully supported configuration. I'm hoping XNET/VFX will work on the HG659 router in future so I can get rid of my Linksys WRP400 device.

Is this possible or is it unlikely.
