I call in for every meeting I can. My hearing is poor; the sound quality on the computer just isn't good enough for me. Then add in that my computer is heavily loaded, so it's ability to encode/decode sound is degraded.

I have a high quality desk phone on a land line (admittedly, VOIP from FIOS, but not via my computer) and I will fight tooth and nail to keep it.

All that being said, I'm comfortable typing in an arbitrary length password on my phone. All I ask is that it be formatted to make that easy (groups of 3-4 numbers with spaces).
