Unable to receive calls, even from other extensions.
We've been experiencing a strange problem over the last week or so. Any inbound calls whether from outside or from another extension don't ring the extension. Instead the call goes to voicemail.
I've changed nothing in the settings for a long time but I checked any way to see if anything changed and it all looks fine. The ringgroup is set to ring the extensions and only go to voicemail after 30s. Looking at the logs there are a couple of things that don't look right. I've pasted a snippet of the log which I think may help. This was extension 202 calling extension 201 both extensions are registered to the same PBXes account. Also when making the call there was no ringtone heard in extension 202 it was just silent for 30s then the voicemail came on.

I've tried switching to another server (www3), I've tried rebooting my router, I've power cycled the handsets, I've recreated my extensions but nothing seems to be working.
Can anyone shed some light on this please? It's becoming a problem not being able to receive calls now.
EDIT: If you need the full log I can e-mail that.

RE: Unable to receive calls, even from other extensions.
Thanks for the reply. The thing is I haven't made any changes to the equipment so can't understand how it has become misconfigured. I set it up 2 years ago and it just worked since then.
I've checked all the settings and they all look fine. The equipment I'm using is a Thompson TG784 ADSL router that also has 2 phone ports. It doesn't have much configuration options on the phone side. It registers fine with PBXes and the two extensions are both able to make outgoing calls without problem. Only incoming calls are affected. Doesn't the fact that it is registering and making outbound calls mean it's correctly configured? There is no ability to configure anything detailed other than the server, proxy, ports and extension usernames and passwords.
When you say "SIP response 404 to standard invite" is the response from my phone do you mean in this case the Thompson router? What is actually happening? If the extension is registered and is able to make outgoing calls why does it give a 404 response?
I'm just trying to understand why after years of working it's now giving problems.
