Update interworking not working

edited Nov 6, 2019 4:05AM in Acme Packet (MOSC) 3 commentsAnswered

Hi,

SIP interface on Realm 2 has:

options 100rel-interworking,update-interworking

Call comes on Realm 1 - call gets routed to Realm 2, B side responds with 183 w/ sdp and starts sending UPDATEs. SBC transmit UPDATE to Realm 1 instead of responding to B side with 200 OK.

It looks like, if INVITE that came to Realm 1 contains "Supported: 100rel", than 100rel-interworking does not function and 100rel is transmited from B to A. This seems logical but this applies to UPDATE messages also somehow.

If I delete 100rel from Supported header with in-manipulation on Realm 1 session-agent, then update-interworking works as expected - not transmiting UPDATEs to A side but instead responds to them.
