Hi Bogdan,<div>Unfortunately I've found that it doesn't fix the entire problem.</div><div>I have a contact now that is online, that still isn't getting pinged for some reason.</div><div>I think there's something subtle in get_all_mem_contacts in dlist.c.</div>

<br>
Thanks God for mentioning this - the initial report from James missed me, and I was not aware of the bug and the fix - I just fixed it right now on the SVN trunk and 1.6<br>
<br>
Thanks and regards,<br>

Hi,<br>
I've noticed after a period of time, Nathelper will stop sending pings to some contacts.<br>
I've verified that the contact is still registered (it is even in the location table) but the ping process appears to skip some contacts for unknown reasons.<br>

maybe see if this fixes the problem for you:<br>

Could someone please look into this? I have phones behind NAT that stop being able to receive calls because firewalls close down the UDP mapping<br>
since this feature is not working properly.<br>
