Skype for Business, IP phone locks

Is there a way to extend the lockout time for my IP phone? How long before it locks?

IP phone lockout occurs after 1 hour of inactivity.  The timeout setting is a universal server-side setting.

NOTE: It is possible to answer calls on locked IP Phones.  If you need to log in during the conversation to perform an action (e.g. transfer the call), select the unlock button and log in.  Once logged in, you may transfer the call.
