Hi Jason,
This reference was to CCM but this can be done on CME as well :)
This can be done on CME on a phone by phone basis. Have a look;
service phone
To modify the vendorConfig parameters in the configuration file, use the service phone command in telephony-service or ephone-template configuration mode. To disable a setting, use the no form of this command.
service phone parameter-name parameter-value
no service phone parameter-name parameter-value
This command in telephony-service configuration mode modifies vendorConfig parameters in the configuration file for phones in a Cisco Unified CME system.
In Cisco Unified CME 4.0 and later versions, support for creating configuration files at a per-phone level was supported and this command in ephone-template configuration mode creates an ephone-template of vendorConfig parameters which can then be applied to an individual Cisco Unified IP phone in Cisco Unified CME.
disableSpeaker {true | false}
Enables and disables the speakerphone.
true Enabled (default).
false Disabled.
Router(config)# telephony-service
Router(config-telephony)# service phone disableSpeaker false

The following example shows how to disable the Speakerphone on an individual IP phone (ephone 15) using an ephone template:
Router(config)# ephone-template 8
Router(config-ephone-template)# service phone disableSpeaker True (**this may be FALSE as there is some debate here)
Router(config-ephone-template)# exit
Router(config)# ephone 15
Router(config-ephone)# ephone-template 8
Router(config-ephone)# exit
Router(config)# telephony-service
Router(config-telephony)# create cnf-files
Router(config-telephony)# exit
Router(config)# ephone 15
Router(config-ephone)# reset
Hope this helps!
Rob
