Hi Larry,
Just to add a note;
Power
Q. Do the Cisco Unified IP Phone 7965G and 7945G models support Cisco inline power?
A. No. The phones support only IEEE 802.3af PoE (Class 3).
Q. As Class 3 IEEE devices, do these phones require a continuous draw of 15.4 watts (W) (standard Class 3 allocation)?
A. No. When Cisco Unified IP phones are connected to common switches such as the Cisco Catalyst® 3560 Series Switches or Cisco Catalyst 3570 Switches, the switch can automatically detect the phone type and provide the exact amount of power that the phone needs. The use of Cisco Discovery Protocol provides this greater granularity to the power classification, allowing for more accurate reporting of power consumption, and a higher density of phones on the switch. The Cisco Unified IP Phone 7965G and 7945G models will draw a maximum of 12W from a switch; this places them beyond the limits of Class 2, but below the default 15.4W value of Class 3.
Q. Is there a recommended powering option for these phones?
A. No. Powering decisions depend on the customer's environment. The IEEE 802.3af inline power method can be used; alternatively, either the standard Cisco Unified IP Phone external power adapter or the Cisco Unified IP Phone Power Injector can be used for local power.
