+2 on Obi for home service. The call quality is outstanding, love GV's voicemail to e-mail transcription. I have passed fax over the 100 & 110, but it does seem to connect at Group 3 faster over the 202.

I keep a MagicJack+ in the computer bag for travel & it's ok, not great. Not as good at faxing as Obi. Probably won't renew just over the $20/year fee as there are too many SIP softphone services available while on the road.
