In this case its probably not an ALG, you should enable rport in your device and NOT force it with the NDLB param, if your device doesn't support it, throw that device in the trash or take a hammer to it, and buy a device from a manufacture that actually made an effort to implement SIP. /b On Mon, Feb 19, 2018 at 6:10 AM, Carlos Eduardo <kaduww@gmail.com> wrote:
It can be an ALG problem (https://www.voip-info.org/ wiki/view/Routers+SIP+ALG). Try running another sip profile with a different sip port, 5070 for example, and register the phone using this port.

Thanks Brian. I should have been more clear. That was exactly my diagnosis and attempted fix using this line:
<param name="NDLB-force-rport" value="true"/>
in the <param> section of the <user> in the Directory file has no effect.
That means one of two things. I am putting it in the wrong file or I must bite the bullet and get FS up to the current version.
Thanks again.

Enable rport, The issue was from 15183 and we respond to 5074, so the device never receives the 401.

HI all,
I have a NAT problem I can’t seem to get past. The phone is NATed. From my location with a FIOS router it works fine. But the client recently upgraded to a new SonicWall router and splat, this device failed. There are about 10 Cisco phones at this location working fine. This phone is a Panasonic KX-TGP550.
I have poured over the sip logs and identified the problem. *The sip packets come from the router IP and port 15xxx but are returned to that IP and the phone’s source port 5060 instead of 15xxx.*
I have tried every NDLB feature I can find, but not every combination. The responses always go back to the wrong port.
Any help would be greatly appreciated.
Thanks,
Sean
