T1 Phonebook Configuration MultiVOIP User Guide
Similarly, the Inbound PhoneBook for the Baltimore VOIP (shown first
below) generally matches the Outbound PhoneBook of the Minneapolis
VOIP (shown second below).
Notice the extended prefix to be removed: 14103257. This entry allows
Minneapolis users to contact Baltimore co-workers as though they were
in the Minneapolis facility, using numbers in the range 7000 to 7999.
Note also that a comma (as in the entry 9,443) denotes a delay in
dialing. A one-second delay is commonly used to allow a second dial
tone to be generated for calls going outside of the facility's PBX system.
