Thanks for the replies guys
Yep tony thats about the height of it to check quality
Was also thinking maybe I could use the sip port on back of it
I had got it working with blueface but it does not appear to be possible to use voip on it while in bridging mode
And there is no phone port on the netgear so if I want to use the trunk I would have to get some other adapter
which would not be a big deal I suppose as i only paid €9 for the netgear
cheers
