Unlock Cisco 8861 Phones

I have 4 phones purchased that came from a lawyers office in Dallas, Tx. I need to have these phones unlocked from your service so I am able to utilize them here on a different carrier. How do I do that and will you PLEASE assist in getting this completed? Thank you.

Sounds like you need to contact Cisco. These are IP phones and I assume you're saying they are registered to an AT&T IP address, for SIP trunks. But I'm not positive that's what you're asking. I do know your not talking about AT&T landline traditional or digital which @ATTHelp gave you instructions for.
