[sr-dev] request for backporting to 4.2 - presence_dialoginfo : optionally send dummy dialog

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 ?
