Cannot Delete Mac Address in Call Manager Router

[michael brock]

Hello, I am not a VOIP engineer, at all, but I am tasked with adding and deleting phones through the CLI in the Call-Manager(Router) I am trying to move a phone but it says the Mac-Address is already associated with another EPHONE. I have deleted that EPHONE and EPHONE-DN that was associated with the MAC address, and they go away. I then try to add the MAC address and it wont allow me. When I do a SHOW RUN | I <Mac address> I see it still in the call manager. I have been able to delete the EPHONE before with no problem, but not this time.

Any help would be greatly appreciated!

Hi, 

Can you paste the part of show run which include the MAC?

Is this phone still plugged to the switch?

Hi Troy

I guess you are talking about Call Manager Express.

Make sure the telephone is powered off otherwise CME will create an ephone for it.

If you want to delete a ephone then change the mac-address statement to something 04aa.bbbb.cccc and then no phone will connect to it. Show ephone summary shows the phones which have sneaked in without a defined ephone statement.

Firstly you have to check that  the IP Phone is removed from the network, do not add any new phone to network 

To disassociate the MAC address from an ephone configuration, use the no form of this command.

 

mac-address [mac-address] [reserved]

no mac-address

Syntax Description

mac-address	Identifying MAC address of an IP phone, which is found on a sticker located on the bottom of the phone.
reserved	Identifies the reserved MAC address of the phone.
