Urk!  Good thing it wasn't an outbound ISD call then.  :)

Bloody hell, this sounds like much the same problem that cursed many owners
of M7Fs, and occurred so frequently with Chris R that he pissed off the
NetComm and bought a Banksia instead (this was at his work though, not at
home).

Are they running M34Fs as well?

That's a serious problem, and it just ain't good enough in a $500 modem. 
In fact, it's bad enough that you might even qualify for your money back if
that's what you want.  Trouble is, what the fuck do you replace it with?  
Maybe Paul Markham will sell you his Courier quite cheaply, if you ask him
nicely.  :)

Hadn't you already determined that -50dBm to be a faulty reading?
