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
