Are you suggesting to combine FreeSWITCH and a SIP Proxy together ? Can you ellaborate about that topology ? I want to retain the unique features of FreeSWITCH in my system. Thanks.

The event-packages of those subscriptions are two, their names are: “dialog” and “p-np-session”. But FreeSWITCH replies 489 Bad Event to SUBSCRIBEs to “p-np-session” and 200 OK to SUBSCRIBEs to “dialog” (because FreeSWITCH implements this package but that’s not what I need) So, is there some way to make FreeSWITCH transparent to those subscriptions (like a vanilla SIP proxy would be) ? Any suggestions ?
