Asterisk 13/PJSIP supports inbound UPDATEs, I see them all the time as
inbound Session-Timer mechanism.
https://wiki.asterisk.org/wiki/display/AST/Asterisk+13+Configuration_res_pjsip#Asterisk13Configuration_res_pjsip-endpoint_direct_media_method
mentions support for SDP renegotiation via UPDATE if supported by the
endpoints being preferred above re-INVITEs.
