CME Voice Register Template to Disable 7821 Speakerphone

[AntDPre]

Hello Everyone, 

 I have scoured the Web and the forums for an answer but have not been able to find one. I have a CME (v12) that supports 7821 SIP phones in a secure area where the speakerphone must be disabled. I have SCCP phones registered with the same CME and disabling the speakerphone for those models is rather simple via an ephone-template. However,  I do not see this same functionality under the voice register template configuration. 

 Does anyone know how to disable the speakerphone for SIP phones in CME? 

Thank you all in advance!

Ant,

I was able to get this to work with 7821 SIP phones registering to a CME running the same version as you.

Unfortunately, with SIP phones / CME, you must manually edit the XML configuration file generated for each phone.

Within the phone's generated XML file, located in the CME flash:/its/ folder, locate the <vendorConfig> tag. Under this tag, add the following line:

<disableSpeaker>true</disableSpeaker>

Once you’ve added this, force the phone to re-pull its configuration (a manual reset typically works). I've tried this method, and it effectively disables the speakerphone.

Keep in mind that running the create profile command under voice register global will regenerate the XML files, which will overwrite any changes you've made manually. You may want to use some sort of script to apply this dynamically.

Hope that helps!
