By default, the dial pad only searches the Local phonebook and recent call history for suggestions while dialing. This adds support for searching the Remote Phonebook if configured and enabled. There is also commented out the definition to search an LDAP phonebook if one has been configured elsewhere.
Add the ability for the "History" to show the original caller ID when picking up parked/intercepted calls instead of the history showing the dial code that was used to pick up the call. The Call History on the phones would show park+*5901 after using a button to pick up a parked call. The Caller's name would display properly during the call but wasn't in the history unless this variable is set.
