Have had Vonage for many months now.
Here's my issues:
911 - you know about. I don't have a standard address so I don't have
this set up yet. Not a big problem, unless I have a heartattack in my apartment
and someone tries dialing it.
Quality : Good quality UNLESS you also have the cable modem as
your internet access. Took me a while to figure out why on some
phone calls, people would say "Are you ok? Your voice sounds like it's
in slow motion." and I hadn't yet opened the scotch bottle up that
evening. Turns out, in my case at least, you can't have the computer
and phone up at the same time (or, what I do, is tell the firewall to shut
down traffic while I'm on the phone.)
Cell Phone numbers: Big issue -- for some reason, if I call cell phone numbers
that are turned off/roaming, it won't switch over to their voice mail -- just
keeps ringing. I end up having to use my cell phone to call them back to
leave messages (?!?)
Not portable : Can't use the phone ports in my apartment. I've heard that you
can, if you go outside and disconnect it from your phone companies main line.
The phone company, even if you're disconnected, still sends a charge through
your phone lines --- if you plug in the VOIP modem, it could blow the modem.
If you disconnect it, then you can use any port in the house (I just can't
get access to it.)
Dropped line: Whenever my local cable company decides to scramble up
my ip addresses, I have to reboot the VOIP modem -- no dialtone and calls go
right to voicemail. Maybe once every 2 weeks. Annoying as all hell.
On the plus:
Love getting notified at work when I get v-mail --- they send the .wav file to you.
Ultra Cheap! I only pay $16 a month where with SNET I was paying $60.
Was able to carry my phone number over!
Overall: If comparing apples to apples, I'd say the service sucks compared to
what you get from the phone company. But, the price tag makes up for the
aggravation. You get what you pay for. So, I'm reluctanly ecstatic!
