SIP allows many devices to be connected for same user, each with its own
presence state. All have to be stored and presented to the watched by the
presence server. To update an existing state, a device has to reuse the same
ETag. So if the PUBLISH requests don't have the same ETag, then both have to be
stored.
Note also that presence states are refreshed periodically (like registration),
so its rather hard to say with one is more relevant at a moment, anyhow, you
have the option to retrieve by time or by priority that you can set via xavp,

In summary, it is not a bug. If you want to discuss more, start a conversation
on sr-us...@lists.sip-router.org mailing list, we keep this tracker only for
bugs or feature requests. If the devices are sharing the same ETag, then reopen
this issue and attach (make available for download) the pcap with the SIP
traffic. If you need a new feature, open a new item on this tracker with the
description of what you want.
