PJSIP syntax error exception when parsing 'From' header on line 4 col 54

I have a problem with registration of one type of embedded device (Lara Intercom) - log below. Only non-standard thing in From field for me is that tag contains “@ip address” marked with **. Can this be solved on asterisk side?
