There was discussion on this in an industry chat I am in and the broad overview is Asterisk may not be affected. That said it was admitted by participants of the conversation that all aspects haven’t been reviewed.

I would think maybe @jcolp may know if this affects the Asterisk implementation of PJSIP as much as or more than anyone

Asterisk does not use pjsua, they are not applicable to Asterisk.
