Summary: Better blf support for linksys phones
Initial Comment:
With current implementation, if there's no ongoing or terminated dialog
registered in the presentity table, presence_dialoginfo sends a notify with
empty body as reply to a subscribe.
This makes BLF support incomplete for phones that only register to dialog-info
event (linksys), so they won't know the state of the subscribed uri until it
makes a call.
The attached patch adds the ability to presence_dialoginfo to build a
dialog-info body that reports the state of a dialog as terminated when there's
no dialog, but we have a presentity entry for that user. Something like:
<?xml version="1.0"?>
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="0"
state="full"
entity="sip:al...@example.com">
<dialog id="sip:al...@example.com">
<state>terminated</state>
</dialog>
</dialog-info>
The patch also adds a contains_presence api function to presence module so we
can check if there's a presence entry registered for a given uri.
I've tested it only with linksys spa-9x2 phones, but it's trivial enough to not
make any other phone unhappy.
This makes support for linksys blf a little better, but it's still missing a
similar notify when the monitored user registers after the subscribe. Right now
the subscriber won't get notified until it resubscribes.
