We will very soon be upgrading from CCM 4.1.3 to version 5.1.1.b
We will also be changing IP Handset signalling from SCCP to SIP.
My question is:-
We are currently using 4940G and 7960G Handsets but we need to implment various security standards such as:-
1) Media and Signalling Encrytpion
2) Utilisation of 802.1x
3) Security signing of Firmware software on phones.
4) Utilisation of 802.3af power delivery via POWERDSINE manufactured 24-Port PoE Midspan AC Input w/Managenent Switch rather than Cisco PoE Switches.
Would the present 7940G and 7960G handsets suffice in this model?
I have been advised to upgrade these handsets to the 7941G and 7961G model.
