Ok, I don't have another modem.

So should I connect the DSL-2730B to another phone jeck and use it for 24 hours to see if theres a problem?

I haven't had a problem for a couple of days now though.

Thanks for your advice,

If you don't mind me asking, I'm having trouble with my PAP2T on the same router.
My old Netgear blew apart in the powercuts we had here in Taupo, so I'm using a DSL-2730B from work in the meantime.
Previously on the Netgear, the PAP2T worked flawlessly, however on the 2730B, it doesn't.
It looks something like this all the time (and calls cannot come in)

Just wondering, what NAT settings and so forth have you got on the 2730B that yours, uh, works :)

Interesting, your SIP messages for registrations look fine which means the responses are get back to you,

try this if you make an outbound call and then phone straight in does it work ?

To make it work at an absolute minimum, I just configured the Xnet PPPoE settings, and configured the SPA2102 to sync it's voice profile with WxC.
I am using the NAT setting, as opposed to Fullcone NAT, if that makes a difference.

To get my router working reliably I have also configured a static IP for the SPA2102, and disabled DHCP on both devices.

Does that help at all?

I should mention that I am still experiencing issues at times where the ADSL connection on the modem appears to drop out and come back again after 10-20 seconds.

Nope. It's weird.

I can register, I can call out, but the caller cannot hear me, and I cannot call in.
I've even chucked in the PAP2T as the DMZ, and no dice.

Okay I took a look at a couple of your calls and the problem is natting at your end basically the SIP messages are not getting back to your device, going out are fine but incoming is the problem, the reason you are not getting audio on your outbound calls is that the outbound SIP messaging is working fine and this rings the phone at the far end, however the message which comes back to you to tell you to connect the call and what port to listen on is not getting back to your PAP2 so dead air the call will then time out and drop becuase it didn't see this message.

This is also why incoming calls to your number do not work at all as we get no response at all when we send the Invite message to you.

Try setting your PAP2 up on a static IP and do a port forward on your router for UDP port 5060 to that IP, see how you go with that.

Well, I'd put it in the DMZ on the weekend (and it's had a static IP since I got it), so if it was a firewall issue, that would have worked.
But, you never know so I put the forwards in, but still nothing.
At the moment I'm working on the hunch that the powercuts last week have done something odd to the PAP2T.
Really odd, for it to be able to be logged into and register etc.
Trying a few tools to see if internally I can send/receive SIP traffic, but failure doesn't mean much since I have no idea if they would have worked in the first place with a working PAP2T.

I guess the last test would be to set up a Softphone, and unlock the VFX from the mac address.
