Get rid of the Cannot Connect Dial:#777 Popup?

[cbreze]

I get this on my verizon tp2, but usually only when tethered. I'm not roaming and have a good 3g signal. It goes away with a click but sometimes comes back. I generally am able to ignore it since my eyes are on my laptop anyway. It seems to have no effect otherwise and my signal is fine so I'm perplexed as to why it pops up. I can certainly see how irritating this would be trying to use your phone.
