I modified a device pool to point to a new callmanager group for some reason

the phone stays with the previous callamanager group settings. eventhough, i manually reset the phone multiple times. i know that the new callmanager group callmanager prefered works because i had a new ip communicator conected to it, and it show it under the settings.

I also noticed that the phones that i am testing belong before to another device pool before the move and keep this settings.can it be that something got stucked?. Another issue that i noticed is

that the old device pool had a srst reference however when i move them to the new device pool with a different callmanger pool, i noticed that it still has the srst reference it it, eventhough new device pool does not have srst reference.?

any sugestions to what to look for?
