Re: [Voip.ms] voip.ms New York outage said by Mango:....The workaround - because technology isn't perfect, no matter how much money you throw at it - is automatic failover.
Both reducing the number of failures, and making unavoidable failures transparent to most end users would increase their perceived reliability exponentially.
While we are on this topic/tangent, would this be the manner in which CallCentric does things ?
They only seem to provide us with settings for ONE server (even though I have gotten my hands on a list of a block of IP addresses for what would appear to be a group of auto-failover mirrors), and has CallCentric experienced perceivable recent outages ?
On the VOIP.MS site the other day, I logged in to see details about possible DIDs, and noticed a trouble log.
I looked at it and discovered, to my anxiety, that there are rather frequent entries for server outages similar to this one - for an hour or two here and there - and Montreal (their 'home town') fails as frequently as NYC - each multiple times this year alone.
OY !

We have only 2 things about which to worry :
(1) That things may never get back to normal
(2) That they already HAVE !

| Callcentric has many SBCs (which you may call servers) in a single location. Though they have no geographic redundancy, you could argue that this would not impact their reliability because Callcentric has historically been extremely reliable.
They do have automatic failover (DNS SRV) that will allow your device to register to a different SBC without human intervention, if one should go down or they should remove it from service. However, I suspect this is secondary to the fact that Callcentric simply doesn't "go down" very often. |

Is that the type of failover functionality (DNS SRV) which some here are saying that VOIP.MS should add ?
I had previously noticed that VMS did not seem to be using that parameter in their settings.
Also, if this method is pretty much an on-the-fly DNS rerouting (as I understand it), then would it not also be fairly easy for CallCentric to put some of their SBCs in an geographically alternately located data centre, to become even more robust than they already seem to be ? |

1 edit | In my opinion, DNS SRV is a good idea. It's not the whole picture, but it's definitely an important piece of the puzzle.
DNS SRV allows you to specify several servers or SBCs and assign them a priority and/or weight. If your device cannot reach the server in first priority, it will use the next one in the priority list.
The limitation is that calls in progress will still be cut off when a server goes down. That's why I say it's just a piece of the puzzle. But unless you're on a call when an issue arises, you will probably never know about it.
Edit: I should have mentioned one other limitation. If the server is not working properly but is still reachable, DNS SRV will probably not help. It's most likely to be effective when equipment is completely inoperable. |

Their whole point is running their own shop.
"We're NOT co-located with any providers - we operate our own data-center (with all underlying infrastructure, under 24x7 video surveillance) with redundant air-conditioning and AC power-plants; our dual-redundant AC sources reside on the same AC power grid with NY stock exchange (which is just across Broadway from us). In fact, we provide co-location, IP and TDM connection as well as origination and termination services to many international operators....."

Should we draw up papers, or is a handshake good enough?
Certainly not good enough. But since I'm in a hurry, it'll have to do.
To get out of Casablanca and go to America....You're a lucky man.
My agreement with Sam is that he gets 25 percent of the profits. That still goes.
I happen to know he gets 10 percent. But he's worth 25.
Abdul, Carl and Sascha, they stay with the place or I don't sell.
Of course. Rick's wouldn't be Rick's without them.
Well, so long. Don't forget you owe Rick's 100 cartons of American cigarettes.
I shall remember to pay it to myself.

At which they surely can boast a very good track record.
said by PX Eliezer:Hell, maybe they could run the server for Voip.MS.
There may have been a joke/poke in that statement, but also some truth.
It DOES seem that Voip.MS could learn some things from them. |

Voip.MS has [many] good things about it.
But they need to get these server issues settled down. |

Agreed. I've set up clients on both voip.ms and CallCentric. I'm on the voip.ms New York server and I've been fortunate to have been completely unaffected by the outages, which I suppose isn't surprising since I think the total number of hours the New York server has been offline in the last 12 months has been under 5 hours altogether, i.e., an uptime rate of about 99.94%. I do understand that for some individuals and businesses, any downtime is a deal-breaker.
Unless there was a more protracted outage, or my clients became unhappy with their service, I'd be hard-pressed to switch over to Callcentric even as I recognize they are an excellent provider. Callcentric's feature set simply cannot hold a candle to voip.ms's. My clients depend upon features that voip.ms throws in for free which CallCentric doesn't even offer at all: multiple registrations (subaccounts), multiple voicemail boxes, IVR and DISA. CallCentric's pricing is substantially higher too, at least based on my usage patterns and those of my clients.
Still, I agree that DNS SRV failover and a unified voicemail system should be a top priority for voip.ms. The sooner the better. |
