I have a hospital that currently has two G6560's with two clans that the phones register to. This particular hospital is an ESS off a much larger hospital. We are in the process of removing the G650's and replacing them with G450's. My problem is how to gracefully push the phones off the clan's and get them to re-register with the procr. We tried resetting phones by IP address but they came back up on the same clan. Any advice would be greatly appreciated. We really do not want to take the clans down and force 130 phones to re-register all at once as this could impact patient care.
