Hope you are all well?

Im currently testing Freeswitch with a blink client to look to send events following RFC4575 /4579.

I am making basic calls to a conference with flag rfc-4579 defined and the client connects to the conference, and FS as expected sends back the ;isfocus parameter on its contact address in the 200 ok.

As a result the client I'm using (blink) sends a SUBSCRIBE, with Event: conference, which FS in turn sends a 202 Accepted response to.

However after this point I get no NOTIFY messages at all to the initial SUBSCRIBE and  for subsequent changes in the conference.

I notice if a SUBSCRIBE for messages, or presence are sent, they are responded to without issue with a NOTIFY from Freeswitch.

Please can someone advise if this is a configuration issue or something else that needs exploring?

Any help would be great.

Many thanks

Jon
