This review covers the Callvantage service with both the D-Link and Linksys routers. I'm not old enough to have experienced it personally, but British sports cars had a great public image after World War II - a small, nimble, sporty car that could ...

Pros: Feature packed service at an inexpensive price compared to a landline.
Cons: Must have cellphone backup for service during a power outage.

2/25/07 Significant update added at the bottom of this review. Original review: Would like to relate my experience with VOIP, since I read so many skeptical and negative posts on the subject. I just had Verizon FIOS installed a few months ago and ...

Pros: unlimited calling for $24.99.travel with your number all over the world

I am sure you will have lots of question on VOIP since it's new and people are not sure, whether to switch from copper to internet? Vonage is better then CallVantage, firstly Vonage ATA/Router doesn't have to be a Gateway, which in case of CallVantage ...

Pros: Excellent Voice quality, easy to configure, QoS
Cons: prone to failures, may need restart at times.

Pros: Call Features
Cons: POOR SERVICE, Numbers NOT portable, D-Link TA Adapter NOT WORKING, No call length log

I recently signed up with AT&T CallVanage business plan. I have had nothing but problems since day one. I first picked up the starter kit at Bestbuy. I hooked up the D-Link TA adapter to my Motorola Cable Modem provided by Comcast. The D-Link TA ...

Pros: Callerid, Good Quality
Cons: NO TRUE 911

I ordered callvantage through their website, recived it in 6 days, we hooked it up and started making calls instantly, has great sound quality and callerid w/ name.
We sadly had to switch to Packet8 because AT&T did not provide E-911 they sent our calls to a non emergency line which if you have this service or vonage you know, Everyone who has vonage is unsafe because at this time they only provide E-911 in 1 state.
