Hi Guys,

Sorry to bring this up again but I see it when performing interopt testing with mobile carriers.

A number of them due to ISUP interworking, have gateways that generate a 183 with SDP, then a 180ringing.

I understand from ready for example this jira case FreeSWITCHFS-3859 SOFIA "183 early media" followed by "180 Ringing" where this is done by design.

I just wondered if this position had changed and if there is a configuration parameter/option that can allow any early media message to be sent back to A leg by freeswitch, in particular a 183 with SDP, then a subsequent 180 ringing, as carriers tend to want to see both.

Many thanks

Jon
