Subject: [reSIProcate] REFER support
Hi all,
Hi guys
I'll need to make pretty extensive use of REFER and I
got few questions about REFER support in DUM
1) According to RFC 3515 REFER request MAY be placed
outside the scope of a dialog created with an INVITE.
It looks that DUM allows refer on in context of
connected InviteSession or I missed something?
[Scott] Take a look at DialogUsageManager::makeOutOfDialogRequest
() API
for sending refer outside of an existing Dialog. Note: the header
file
defines a makeRefer method - but it is not implemented.
2) Is it possible to construct REFER with replace
header, when UA issuing REFER does not participate in
the dialog to be replaced and got its ID by some other
means (for example using subscription to Dialog Event
Package)?
[Scott] You should be able to just add a replaces header to the
message
returned by makeOutOfDialogRequest, before calling send.
3) How NOTIFY can be correlated with REFER in case of
overlapping REFER subscriptions?
[Scott] Have a look at the AppDialog/AppDialogSet stuff. You could
also just look at the DialogSetId of the messages to match.
http://wiki.resiprocate.org/wiki/index.php?
title=DUM_Associating_Applica
tion_Data_with_DialogSets_and_Dialogs
If all else fails, you can look at the Event header field of the NOTIFY.
If you have more than one outstanding REFER inside a dialog, 3515
requires all but one of them to have a non-empty ;id= parameter on
the Event header field value.
Thanks,
Boris
