This is a 48-u chassis with a 64 license upgrade already applied and active. When trying to register the 57th and higher phone, the phones will NOT register. The following message is displayed on the bottom of the phone:
SPCP register token rejected. Retrying...
It never works.
Anyone seen this and have a fix before I call TAC with a level 1?
