ata w/router instead of dumb ata

[fergessen]

I'd like to clarify,
we have NO need for user-controlled (unlocked) devices.

I only added mention of that to show the extreme opposite experience we had with our voip service with the other provider.

The question remains, what the heck is the benefit of a router/ata instead of an (even locked) ata standalone device?

Again, especially, since the time (money) is required for tech support to do sessions to fool with ports, network topography, and STILL cannot remotely reload firmware or user settings without taking over via VNC.

ALSO...

There have been a number of instances where numbers I dial result in a fast busy.
When I've had the time to do "live chats", the incredibly responsive VOIPo staff has been kind to "re-route" calls.

HOWEVER, I NEVER had this issue with needing "operator assistance" when using Broadvoice (OR my cell or landlines.)

Why is intervention needed (repeatedly) ?

This can't be cost effective. It ISN'T time effective.

Thanks in advance for your explanation(s).
