I recently ported my two Vonage lines to AT&T CallVantage because I could get a $5.00 per line discount by also having an AT&T wireless account. The questionable long term survivability of Vonage also was a factor, but at this time the lower price for the same class of service was the trigger.
A major (for me) advantage is that the AT&T CallVantage service/ATA is able to utilize the load balancing features of my dual WAN DI-LB604 router. With the Vonage service/ATA(s), I had to setup the router to only use only one WAN port for VoIP. I don't know if this is due to the hardware/firmware in the AT&T ATA (D-Link DVG-5102S), or to how the AT&T servers handle SIP and RTP traffic, but it was an unexpected pleasant surprise.
The only operational downside so far is with the AT&T CallVantage voice mail. There is no way to disable it, and no matter how I setup the "Locate Me" function to forward unanswered calls to my cell phones, voice mail usually gets left with the AT&T CallVantage voice mail (which I have setup for the maximum 10 rings) instead of the AT&T Wireless voice mail. That means that the $5.00 per month discount will likely be eaten up by charges for the three text messages that get sent to the cell phones for each AT&T CallVantage voice mail.
The only real problems were related to delays in porting the two phone numbers, and with canceling the two Vonage accounts (one of them is still active after several attempts to cancel), but neither of those problems are related to the AT&T CallVantage service.
