Also, please check to see if the switch to which the 9971 is connected
has CDP enabled. Phones 9971 + camera uses CDP for power distributions
and negotiations. If switch does not have enable CDP the switch will
give to the phone (only to the phone) 15.4W, which is the maximum power.
By giving all the power to the phone, the camera will not work because
the camera as it will need 1.45 W.
I am running all Cisco switches.. The options to enable video on the device is there. I am still open to ideas. I am on the latest CM7.1 code
If you haven't solved this yet, I think I can shed some light.
You're phone is probably being power with a external power supply.
Even though, as it's been said in this thread, if you connect it to a Cisco Switch, you'll still get the same problems.
As long as the power is distributed to the phone via a non-cdp non-poe non-cisco unit the phone can't controll the power to the camera attached.
You need to get your hands on a 3560 switch for example and enable cdp both on the network side of the phone and the switch your're connecting it to.
Unless you have connected expansion modules to the 9971, this should be more then enough power, even without the V2 switches.
I have a 9971 with both PSU and PoE and it seems as long as the phone does have a CDP unit controlling the power consumption, the camera operations are OK.
Imho this is a bug of some sort. This forces the consumer who want video capabilities on their phones to deploy cisco poe devices in their network.
That said, it's cleary the best choice, but still it seems there should be more freedom of choice in this matter.
Hope this helps you out some.
