6.2 Establishing a Connection by Callback
The callback function enables the INSYS GPRS/EDGE 5.0 serial to establish a con-
nection to one of the previously defined remote terminals, when calling from a
certain phone number. The remote terminal can be a phone number, an IP address
or a hostname with domain. The callback is triggered as soon as a call from a pre-
viously defined phone number is indicated at the device.
Permitted phone numbers are stored and linked to a destination address (IP ad-
dress, domain name or phone number) in the configuration.
In connection with the function CSDPRIO (see Chapter 4.3), it is also possible to
trigger a callback if the called INSYS GPRS/EDGE 5.0 serial has a TCP connection or
is dialed into the GPRS network in the operating mode TCP Listen during the call.
The connection setup can be set with a call using the HSComm. Click on the
"Connections” tab.
The callback function can be activated via the HSComm by enter-
ing the phone number and selecting “Callback”.
In the next figure, as an example, the number 1 to trigger the
calling back of a callback number (see AutoDial destinations), the
number 2 of an IP address with port information, and the num-
ber 3 of an URL with port information is allocated.
