Masking Alive texts. (only available in ver 1.6 or later)
This feature allows you to mask the Alive text so only the programmed users will receive the
Alive text and not all users. The default setting is all users will receive the alive text but once
this command has been sent only the programmed numbers will receive the text.
To set mask:
Command: Add +??XXXXXXXXXX to alive text (example [phone])
This will set the mask and only the number as per above will receive the alive text, repeat this
for all users that require the alive text.
If everything is fine, the system responds with:
The number has been added to the alive text list
