Where did you get this from?

from": "{contact}"

Please provide a link to the documentation where you found this parameter.

I already tried without the from but the result was the same.
I already tried like that. using the cell phone directly.

<entry key='sms.http.url'>http://192.168.102.90:8082</entry>

I've tried with a standard url to trace but without success.
