Call Transfer
The EVM can transfer a call to an internal phone, a group external phone, a special external phone
or a mailbox owner’s personal external phone.

SYS_1 is used to define the extension numbers to identify internal phones and group external
phones.

Special mailboxes (9900~9989) are used to store special external phone numbers and the related
Remote Switch Access numbers.
Call Forwarding
A one-digit number (0~9) or an extension number included in a General EXTN Group is possible
to be assigned to an internal phone, a Special External Phone or a Hunt Group, or the mutual
mailbox, by using the Call-Forwarding List
ADM_5_[N~] .
Service Operators
Service Operator is the destination to which callers needing help are transferred.
When a caller dials the Operator code or does not respond to a main greeting or an operators’ Busy
Prompt, the call may be disconnected, or may be transferred to the specified operator.

ADM_4 is used to specify service operators.

SYS_3_0 determines how the EVM processes the call that a caller does not respond to a main
greeting or the operators’ Busy Prompt

SYS_3_5 determines the Operator code
Hunt Groups
A Hunt Group identified by a group number is a group of internal phone numbers. Group numbers
(*001~*008) are only used in the Operator Number List (
ADM_4 ), the Call-Forwarding List
( ADM_5 ) and the Receptionist List ( ADM_6 ).
To transfer a call to a Hunt Group extension, the EVM will hunt out an available Hunt Group
extension according to the specified Hunt mode:
Circular: hunting starts after the available extension found by the last hunting. If all of the Hunt
Group extensions are busy, the caller hears the Busy Prompt.
Linear: hunting starts from the first extension of the Hunt Group. If all of the Hunt Group
extensions are busy, the caller hears the Busy Prompt.
Up to eight Hunt Groups can be created by setting the Hunt Group extensions. A large Hunt Group
can contain up to twenty-nine internal phone numbers; a small Hunt Group can contain up to four
internal phone numbers. The programming of a small Hunt Group contains five settings: the first
four settings can specify only internal phone numbers, an empty value of which indicates end of the
group; only the fifth setting can specify the Hunt Mode option of this group and of the related large
Hunt Groups. If the fifth setting specifies an internal phone number, this group will be a large Hunt
Group to subsume the next group.

ADM_5_9950 ~ ADM_5_9954 are for setting *001 Hunt Group.

ADM_5_9955 ~ ADM_5_9959 are for setting *002 Hunt Group.
