Full list of reserved and available numbers in Pilot Voice

    This list details which numbers can and cannot be assigned to users in Pilot Voice.

    Introduction

    We’re all about helping you customize your Pilot phone system, but there are some numbers that just can’t be changed. 

    The table below shows which digits are off-limits and should not be assigned within a domain (sorry—even if it is your lucky number!). 

    Numbers reserved for system functions

    00-99
    Reserved for internal use
    611
    Customer Service
    911

    700-799
    Used for Dynamic Call Parking Queues
