Inbound SMS not handled

Hello,

I will be really grateful if someone could help with this.

I have playSMS and Kannel gateway working.
Kannel receives inbound SMS via SMPP connection.
But conncection between Kannel and playSMS seems to be missing something – in playSMS log I could not see the destination number - it is replaced by Global Sender from configuration of smsbox .
Here is the log:
2018-12-21 16:13:09 PID5c1cf4f532078 - L2 kannel__call # start load:/var/www/html/playsms/plugin/gateway/kannel/geturl.php

Any ideas what is wrong here ?
