Notes on the line configured for SMS
When calls from the SMS provider are forwarded to the 704PC LAN SMS line,
- there is no compatibility check
- any call forwarding configured for this line is not performed
- there is no validation check
- call waiting is not signalled.
If there is a telephone call on the SMS line, calls from the SMS provider will be
rejected, i.e. a short message does not trigger off a call-waiting signal.
