Hi all
Now that Google talk (email phone calling) is charging for US calls, I was looking for a free VOIP service and I came across whisper phone. The only issue is, I cant get it to work because it needs SIP disabled.
I telnetted in to my modem (the telecom modem, Thomson TG585v7) using these instructions (except I did it from my Mac and terminal)

but I keep getting this error: FAILED TO DELETE CONN BINDING

Can anyone help me beyond this point so I can get the VOIP phone to work? ANY feedback appreciated.
