Connectivity Issues with sip.voipwelcome.com

[VOIPoBrandon]

Tritch,

The scenario you describe is completely different than SpaethCo's logs. He has a registration interval of 1 minute as well as OPTION ping requests he is sending us in which he is stating that our response to requests are delayed. I tracked each of his requests and as you can see an actual delay in response is few and far in-between and certainly not service impacting.

As for your call to your father --- it could have routed to failover for a number of different reasons, however this typically means that we did not receive a response back from your Father's endpoint / device to our request to initiate the call. So you can see here we are talking about two completely different scenarios.

Also there is not really a such thing as dropping out of registration in-between registration intervals since the actual registration interval is what determines in 99% of the cases the next time of request for registration. So in which case we would still have maintained an AoR (Address of Record) that we could contact the endpoint at given there are no firewalls preventing our request. This is of course unless the SIP device / client is doing some kind of odd rebounding logic in which it thinks its loss connectivity to our network.

Thanks. I stand corrected. I probably should have said that in-between registrations it was losing the "ability" to communicate with SIP server even though the lines showed registered. There's no doubt that I was seeing sporadic loss of registrations on his lines in vPanel up until Monday. His problems were identical to what others have posted.

The failover problem this morning was symptomatic of the same registration/connectivity problems that have been affecting most of the BYOD folks over the past week. I just assumed it was the same ongoing issue. His ATA is in the DMZ of the router, so I doubt it was a response or firewall issue with his device.

Is this case considered closed? I'm assuming all the support tickets have been cleared up.

The expiry interval for registration is actually 120 seconds (asterisk always renews at expiry-15 seconds, so 105 seconds in this case).

In any case, I'm updating the case with packet captures to show the behavior that is concerning. There are periods of time where the server simply stops responding to all SIP requests -- registration, options, invites. I'm sorry, but that is service impacting when call setup traffic is not being processed.

Tritch,

As of today I am still having issues although not as bad as yesterday. Brandon has been very helpful in trying to get to the bottom of the problem. I agree though that because it is so sporadic it is a bit frustrating to know when a call will work or not work, especially on incoming calls. My guess is that it is not very widespread but still an issue for some of us.

A bit frustrating? Imagine how us resellers feel. Reseller accounts are all on the BYOD server. Customers complaining non stop. Some even threatening to cancel.
