[cisco-voip] a strange flood of packets from ccm

An IP phone will maintain a TCP session, and send skinny keepalives, to
every CM that it could potentially be registered with (ie in its CM group).
Only the CM that it is currently registered with will respond to the
keepalive though.  The message below means that CM was a backup CM for that
particular phone, so there was no need to respond to the keepalive.  It is
not related to your problem and is completely normal.
