NOTE
With a GSM connection, we strongly recommended using the RBIP or SCAIP protocol.
Please refer to the
Reference Manual
for more information on programming.
Other protocols are accepted, but they will be transmitted through the GSM voice band.
The quality of the communication depends on the chosen protocol, the GSM signal level and
the service provider.
NOTE
Be aware of potential limitations due to network availability. Prioritising an emergency call
may not always be possible.
