[reSIProcate] Multiple handles for same session

[Scott Godin]

This is a forked call.  These two dialogs should have matching
DialogSetId's.  How are you ending a session when you "disconnect"?  If
you call InviteSessionHandle->end(), then only that session will be
BYE'd.  Once one end of a forked call has been answered, the other
session will be automatically destroyed (onForkDestroyed) by DUM 32
seconds later, if the application does not explicitly end() the session.

Subject: [reSIProcate] Multiple handles for same session

 

Hi,

Wishing all a very Happy New Year 2007 !!

So here it goes ... perhaps the first prob. for 2007 :)

The scenario:
I make a call to some peer UA (let's say A ). Now A is registered with
Sipx SIP Proxy and is available. On receiving Invite, it sends back 180
Ringing. Now nobody picks up the call at A, so after some time Sipx
Proxy takes the chargs and sends a new 180 Ringing (the to-tag is
different in this, but the branch is same) followed by a 200 OK and the
recorded message starts (IVR).

The problem is that the new handle in onNewSession does not match with
the previously stored handle. But if I disconnect immediately, DUM sends
two BYE for each of the dialog. However, if I disconnect after some time
(say a couple of minutes), the previously stored handle is not valid at
all, so I am not able to close the call to proxy ... It seems I should
store the newly received handle for future actions, but what happens to
the previous one, is it destroyed automatically by DUM or not. If yes,
how !! ... and if no, is it a leak ?? 

Right now I refer DialogId to match handles, but is there something else
which I can refer through handle to match these two handles of same
branch but different Dialogs. This would save me storing a new handle
for same session everytime  !! 

Thanks,
Nilay
