SMS Security

Inbound SMS Messages

Incoming SMS messages are received as UDP packets, and forwarded to the
local device IP address and port. The UDP packets are in the same format as
sent messages.
When Trusted Phone Number security is enabled, incoming messages coming
from the phone numbers in the Trusted Phone Number list are the only ones for
which commands will be performed (relay, response etc.) or gateway messages
forwarded. Incoming messages from all other phone numbers will be ignored.
Commands sent to the device with the correct password are always treated as
coming from a trusted number.
All non-alphanumeric characters except a space will be replaced by a dot in
ACEmanager.
