[Example of a DTMF Command Sent to the VPS]
Conditions
• After the VPS answers a call, the PBX sends Follow on ID information to the VPS. The amount of time
before the PBX sends this data is programmable.
• After the VPS transfers a call to the PBX via AA service, the PBX sends a DTMF status signal to
indicate the status of the called party. The amount of time before the PBX sends this status signal is
programmable.
• The amount of time (inter-digit time) between each individual DTMF tone sent by the PBX can be
specified through system programming.
• The length of each DTMF tone sent by the PBX can be specified through system programming.
• By default, each extension's and ICD group's mailbox number is the same as its corresponding
extension number/floating extension number, however, a different mailbox number can be specified
through PBX system programming for each extension and ICD group. The specified mailbox number
will be used when "Mailbox for Extension" is set to "Programmed Mailbox Number".
• In order to achieve proper recording quality, Data Line Security is turned on automatically for extensions
in a VM (DTMF) group. (→ 1.10.5 Data Line Security)
