You need to update Asterisk to a version with tel URI support.

Chan_PJSIP Tel URI support now in Asterisk...also v16 final release

Asterisk just released 16.29.0, 18.15.0 and 19.7.0 that now have Tel URI support for Chan_PJSIP. It will now accept Tel URI incoming requests, however, Asterisk still cannot generate Tel URI headers for outgoing requests. Also, 16.29.0 is the last supported released of v16 which is now officially Security Fixes Only.
