[OpenSIPS-Users] strange issues with presence messages

[Alex G]

yes. currently am not using the presence module and letting the phones
communicate peer to peer. I have been running a test with 2 phones on public
ips. So far there is no drop in presence communications between these 2
phones. its only happening when 1 or both of the phones are behind nat.

am going to further research by doing more sip captures, but from what I've
seen of current captures I've done, all seems well... its just occasionally
it seems packets that are presence related are not getting through...

am I possibly using the nathelper module incorrectly? or does it not apply
to these notify.subscribe messages for presence?
