The speaker green lighted indicates that phone is writing images to its flash memory, this could be caused by an erased memory or the phone is corrupted, after this it should display Cisco System logo, if this takes too long time ( 10 minutes or more) ,maybe you have a bad network port or a bad phone.

You have a bad hook switch. The phone has to be disassembled to repair the fault. Refer service to a qualified person.

Make sure you have the phone configured as the correct device type in callmanager. Also, try and turn on auto registration in Callmanager as this will allow everything to register. Then go back and put the correct configuration the phone.

Connecting a hub or switch to the "PC" port on the back of the phone is not a recommended best practice by Cisco as the IP phone does not support spanning tree protocol.

what are you trying to connect this to? cme

Hi,

the DHCP server should be providing the address of the TFTP Server as DHCP Option 150. The most likely problems are:

Option 150 not defined, or not the correct IP address of the TFTP Server.
Or possibly your TFTP Server is not functioning properly.

If you have not Option 150 defined, the phone will use the default gateway as the TFTP server address.

This is configured fromt he backend system. Ask you admin.

You would need either a call manager or call manager express to configure the phone and connect to the phone line.

Is the phone connected to a POW (Power Over Ethernet)Cisco Switch? Check the model number of the switch with the Cisco web site www.cisco.com

Have you check whether there is power available on the switch?
enter "show power inline" at the command prompt.

Does the phone work without the head set?
Does the same thing happen when you plug in the head set on another phone?

It is possible for them to monitor voip calls, if your call passes through their network, or they do remote monitoring on network traffic. The voip traffic is only data that needs to be 'reassembled' to hear the voice stream. However, this is more difficult if the traffic is encrypted between the phone and the call manager or whatever they are using.

I am no legal person, but I am sure that you would have to have agreed to have your calls monitored for them to be able to do this.

OK I am gonna throw an idea at you. Give more details...
I would guess that depending on your configuration your phones are unable to load whatever ring type you called for at the current location. example: I pre load the phone at site "a" with ringtype 1, but ring type 1 file does not exist on current branch server.. just some thoughts... let me know if this can help.

You need to create a call group for transfering. Secondly, you need to configure the caller id within the fxo module.

ask your administrator to change it.

I would check the firmware on the phones. Also, check that your switches are properly configured. Duplex settings do matter. If your using cisco switches; do a "show interface" and check for CRC errors etc.

check your volume level. (press the volume button) and be sure to save the settings.

The handset piece is interchangable. The firmware is NOT. The handset is simply the piece with the speaker and mic in it that you hold in your hand.
