Product: TANDBERG Codec C20 Software version: TC4.0.3.243792
SW release: 2011-01-25
Hello,
I have a C20 with a TC4.0.3.x old release, i would like to upgrade it to a later version to be able to make H323/SIP calls with an alias in front of the IP with direct connection (no gatekeeper). For instance: alias@IP. From my understanding this version TC4.0.3.x doesnt enable this type of call.
How can i upgrade safely from TC4.03.X which is obviously an obsolete version from 2011 now ? From TC4.x to TC5.x? then TC6.x ?
How can i get the release keys from Cisco to ensure the upgrades will not be rejected due to missing release keys?
Thanks for your help.
