What causes an SPA112 to send SIP 410 in response to an invite?

One of our customers had an issue this morning where the ATA appeared to be online (responsive to SIP Options requests) but would always send a SIP 410 response when it received an invite.  The problem was ultimately resolved when they rebooted the device, but the user was very upset that their phone wasn't working.  We have been unable to reproduce the problem in our lab.

Here is the SIP output captured with tcpdump:

11:23:39.375199 IP (tos 0x0, ttl  64, id 57660, offset 0, flags [none], proto: UDP (17), length: 1092) [SERVER IP].sip > [PHONE IP].sip: SIP, length: 1064

What causes an SPA112 to send SIP 410 in response to an invite?

I've done a fast search in google about "linksys sip 410".

Seems to be linked to this option "Ans Call Without Reg".

If setted to Yes fixes the problem.

Sounds strange.

Thanks for the quick response.  I will try that setting.  Are there any security risks associated with allowing inbound calls without registration?

I think no but I suggest you to enable the "Restrict Source IP" option.

Great, we actually already have that option enabled.  Thanks for your help.
