<p><font size="2">Hi List,<br>
I've got a 7960 that's behind NAT (nat_enabled: 1 and<br>
nat_received_processing: 1) and for whatever reason doesn't seem to<br>
register, or at least hold a registration. If both the phone and the<br>
router (netgear) are rebooted, the phone will register, take a few<br>
incoming/outgoing calls no problems, then a few hours later, it drops the<br>
registration and never re-registers. If the phone itself is rebooted, I<br>
see a mess of registration attempts via SIP channels:<br>
7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx:<br>
REGISTER<br>
7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx:<br>
REGISTER<br>
7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx:<br>
REGISTER<br>
7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx:<br>
REGISTER<br>
7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx:<br>
REGISTER<br>
7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx:<br>
REGISTER<br>
<br>
Is there something that I'm missing. Short of replacing the customers<br>
router (which I have admin access to) is there anything else I should try?<br>
Any sort of packet filtering is disabling, nat is enabled in the SIP<br>
config, and port forwarding was also setup to forward 5060-5070 TCP and<br>
10000+ UDP to the phone to no avail.<br>
<br>
Note that if the phone is plugged directly into the customer's modem (thus<br>
removing the router out of the picture) the phone works perfectly.<br>
<br>
Thanks - Any input is appreciated<br>
<br>
