tel-dialer can match contacts by name or numbers and can be used to start calls to both friends in your phones contact list and unknown numbers.
It uses the termux-api to start calls which requires the permission for phone.
Can be launched with key-combo 
If calling tel-dialer without args results in error with no output then you likely need to update your contacts file with tel-dialer -u.
