no devices listed in vPanel

[VOIPoBrandon]

I'm getting no devices listed in vPanel this morning. No dial tone & incoming calls go straight to failover (voicemail). I entered a ticket, but figured I'd mention it here in case others might be offline as well. My service w/the PAP2T has otherwise been rock solid to this point.

Tom,

Sorry to hear about this recent experience. Lets see if we can't figure out what is going on. I have quickly took a look your SIP traffic coming to our network from your ATA. I do see that your REGISTER requests are making it to our network. However generally in SIP based authentication the way it works is as follows:

ATA SENDS REGISTER REQUEST -> VOIPo
(this is done without any *Proxy-Authorization header)
VOIPo REPLYS WITH 401 Unauthorized -> ATA
(this is done because there is no credentials in the original REGISTER request)

Now here is where it looks like the problem lies, if the ATA does discover and "see" the REPLY to it's REQUEST, it will then continue and send another REGISTER request -- however this time containing the Proxy-Authorization request header -- and as long as your realm / hash / etc is valid you will be registered.

Now here is where the problem appears to be happening. Your ATA is not receiving our 401 response to your REQUEST. Which only leads me to believe ports are not forwarded -- or are not forwarded correctly? However also if seems have been working just dandy in the past, it also makes me ask "What changes have happened recently"

*Proxy-Authorization Header: A header that contains your SIP credentials essentially, to authenticate with the proxy.

Disclaimer:
Sorry for the technical explanation but I wanted you to see why we're saying the ports needed to be forwarded and that we weren't just giving you a blanket reply.
