CUCM - Voice port external number mask

[Jesse3620]

Quick question: 

I want to change the 'External Number Mask' field under Directory Number Information for several Voicemail Ports in CUCM. After I save and apply these changes in CUCM, will I need to reset the port group in CUC for the changes to be successful? 

Thank you,

I think you'll just need to reset the voice ports in CUCM.  But no harm in resetting from CUC as well.

Correct, since no changes are made on CUC there is nothing to reset there.
