I asked this question to support and they told me it would be unlocked and able to be used on another service. I received my first ATA (the included free one) and it appears to be locked. Cannot even access the web interface. If I order more, will they also be locked?

I would like to order these for my customers from voipo so they will be automatically provisioned, but if they're locked I won't do it. I'm not going to invest in hardware that I can't use elsewhere if it becomes necessary.

If I do buy my own ATAs, is it possible to have them provisioned automatically by adding them to the hardware list, or will I have to do it manually or set up my own internal provisioning server?
