It is possible to setup sending events notifications via SMS to the managers' mobile phones and/or 2FA OTP-codes.
For sending events notifications the manager should allow it in his or her personal cabinet and specify phone number.
The path to external program with two obligatory parameters is indicated in the start command:
%PHONE% - mobile phone to sent SMS on it (UTF8 URL-encoded);
%MESSAGE% - SMS message text is sent (UTF8 URL-encoded).
The program must implement the sending.
The sending itself may be processed in any way. For example, via public paid SMS gateways by using of various http requests.
