Hi List,
some sip clients like Bria and some sip phones like Astra
expect a <dialog-info><dialog></dialog></dialog-info>
on the NOTIFY message sent.
presence sends a NOTIFY after the SUBSCRIBE with NULL body if it doesn't find the
presentity.
the patch already in master allows to configure the creation of a dummy dialog to be sent
when presence doesn't find the presentity.
this behavior was only observed in dialog subscriptions so the patch was made against
presence_dialoginfo.
the new param force_dummy_dialog defaults to 0 to preserve existing behavior.
using this patch Bria, Astra started working with BLF and others (Cisco, Polycom, Jitsi)
kept running.
does anyone have anything against backporting this to 4.2 ?
Best
