Hi,         

                My  SIP User-Agents need to establish between themselves a mesh of SIP subscriptions (using SUBSCRIBE and NOTIFY).

                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 ?

Many Thanks.
