Pjsip problem with tel schema in To header

I’m upgrading from chan_sip to pjsip, in version 13.19.2.
I have a problem with the incoming calls that have in the To header: tel schema: in these situations it returns the error 416 Unsupported URI Scheme

The flow and configuration:

The tel: URI scheme is not supported in chan_pjsip as of this time.

Is the implementation planned?

I know of noone actively working on such support.
