Pool Dial-Out Code (Hybrid/PBX Only)

Use these instructions only if the system is operating in Hybrid/PBX mode.
The factory setting is for all extensions, including data stations, to be restricted
from using all dial-out access codes. You can unrestrict data stations to allow
the user access to one or more trunk pools by dialing the pool dial-out code.
The dial-out code restriction places data calls only on specific trunk pools. For
example, you may want to restrict users to trunk pools that are made up of
special data lines such as PRI channels used for data services, or to reserve
other trunk pools for voice communications only.
