[cisco-voip] 7962 Phone Sets Failing Authentication

[Ryan Ratliff]

What load is coming on them?  If it's old enough it can't go straight to 9-2-1 and has to hit an interim first.

We have recently received several boxes of new 7962 phone sets from the Cisco factory.  We are running call manager version 7.1.5.34900-7 on MCS servers (Linux).  When we take several of these new 7962 phone sets and plug them into the network port they will pull a TAPS number successfully but fail the authentication and software upgrade portion for phone load SCCP4.2.9-2-1S..  Is there a known work around or middle firmware version we need to load on a TFTP server to update the phone sets?  Thank you in advance.
