I've been struggling to get a stable NAT config on these forever :) Be sure the Netgear doesn't have a stateful firewall enabled (I believe 'SPI' is what they label the checkbox). These cheap boxes tend have flat 5 minute timeouts on UDP port translations and those kill the SIP port forward. The phone keeps sending new registration requests as it is not receiving the reply back through the NAT box. Not even setting qualify=yes will fix these sometimes (this should keep the port forward active and keep most NAT devices from timing out).
With the Cisco, you can also telnet to the phone and force it to manually register on demand (ex: 'register 1 1') instead of rebooting, but usually useless once the NAT device flakes out. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, December 06, 2007 21:14 To: asterisk-users@lists.digium.com Subject: [asterisk-users] 7960 Won't Register Yet Multiple Attempts? Hi List, I've got a 7960 that's behind NAT (nat_enabled: 1 and nat_received_processing: 1) and for whatever reason doesn't seem to register, or at least hold a registration. If both the phone and the router (netgear) are rebooted, the phone will register, take a few incoming/outgoing calls no problems, then a few hours later, it drops the registration and never re-registers. If the phone itself is rebooted, I see a mess of registration attempts via SIP channels: 7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx: REGISTER 7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx: REGISTER 7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx: REGISTER 7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx: REGISTER 7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx: REGISTER 7X.183.246.XXX (None) 000e8XXX-5d 00101/00220 unkn No Rx: REGISTER Is there something that I'm missing. Short of replacing the customers router (which I have admin access to) is there anything else I should try? Any sort of packet filtering is disabling, nat is enabled in the SIP config, and port forwarding was also setup to forward 5060-5070 TCP and 10000+ UDP to the phone to no avail. Note that if the phone is plugged directly into the customer's modem (thus removing the router out of the picture) the phone works perfectly.
