Message output

DECT Messenger supports the following output:

• DECT E2 messages (up to 160 characters)

Although DECT Messenger supports up to 160 characters, the DECT

equipment or the handset can limit this number to 128, or even 48,

characters. If the handset supports only 48 characters, the message is

broken into sections and sent in parts to the handset.

•

Messages sent to Ergoline or DECT extensions during ringing and after

a call is connected

Each device type can specify message length. Messages that are too

long to be displayed are broken into sections suitable for the display

devices.

•

SMS messages to cell phones

DECT Messenger can send SMS messages to cell phones. A modem

or a box that behaves like an actual cell phone with a Subscriber

Identity Module (SIM) card can be the interface to the cell phone

provider.

This option is mainly used as an alternative device. You can forward

the message to a cell phone if a message to a DECT handset is not

acknowledged.

•

E-mail messages

DECT Messenger can send e-mail using Simple Mail Transfer Protocol

(SMTP) to any e-mail server.

• Digital output to control relays or similar equipment

In the event of an alarm, use the relay contacts to control equipment

such as lamps, door-contacts or hooters. Contacts are used as

alternative devices (overflow) in case a message is not confirmed.

• ESPA 4.4.4 pager protocol

DECT Messenger can send messages to paging equipment using the

ESPA 4.4.4 protocol.
