Add me to the happy Ooma user list. As for glitches, I tried to 'not' prioritize the Ooma by putting it behind my network router, but it's like listening to fireworks sometimes. But once I put the Ooma in front of the router, the ONLY problem I've had in 2 years is a glitch they had in the caller ID.
I'm paying extra (a whole $10 a month) to have full Caller ID and a second phone line and number- it's cool because all phones ring regardless of which number is called, and the second line is always available for someone else to use, and can be answered if a second caller calls... Also, every incoming and outgoing call is logged, you can blacklist any numbers, etc...
The only other charge besides the $120 a year is $4 a month in taxes and fees... My old phone setup for 2 lines was $129 a MONTH.
The only thing I miss is the fax machine...
