Hi,<div>I've noticed after a period of time, Nathelper will stop sending pings to some contacts.</div><div>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.</div>
<div>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</div><div>since this feature is not working properly.</div><div><br></div>
<div>Thanks.</div><div><br></div><div>-- James</div>
