Could you please let me know whether the latest Asterisk has a support for inbound UPDATE ?
In my case, the carrier is sending an UPDATE to change the codec which is replied by 5xx from Asterisk 11.17.1.
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.
Thanks, in my case I need RTP to pass through Asterisk. So in this scenario, is there a solution within Asterisk to accept UPDATE request coming from Carrier and act appropriately ?
