Number display and SMS for internal numbers only

Hello. Tell me please,
I plan to use Freepbx 17 only
for internal telephony and I have
2 main questions. 1 - How do I make
sure that when an incoming call is displayed only
the incoming number 100 (without @192.168.0.118)?.
2 - how do I enable SMS messages only
for internal communication? If you can answer,
then in steps where and what to click, I will be very glad to answer.
