Connection via Internet
The connection for remote configuration is established indirectly over the
Internet. The connection session starts with a voice call from one of the regis-
tered phone numbers. During the call, connection parameters (IP address,
keys) will be sent using a DTMF sequence. Afterwards, the Forum 523/524
communications system establishes a secured SSH connection to an Internet
server. The existing SSH connection allows to reverse-connect to the
Forum 523/524 communications system’s configurator. For this type of
connection, the Forum 523/524 communications system utilizes your
Internet account. Establishing an SSH connection via this Internet account
must be allowed for this purpose.
The manual activation of the remote configuration activates the DTMF evalu-
ation for the next voice call. You can add additional phone numbers for remote
configuration on the configurator’s Telephony: Extended: Remote service
menu page. Activate the
IP
option for the desired phone numbers.
