VoIP with 3rd Party Provider
-
Hey guys,
I really appreciate all the info you have given me here. It's definitely given me a good place to start in trying to figure out if we are going to be able to fix this issue or if its going to be an ongoing thing.
kejianshi: We have a Fios Business account with no cable service. We have a fiber cable coming directly into the Fios modem which we then plug up with ethernet straight into our pfSense machine. Obviously, I have no idea what they are doing on the other side of that fiber cable so they very well may be doing something that is causing us headaches over here regarding the VoIP.
I have been testing a call all day waiting for it to drop and currently it has been connect for 5 1/2 hours. During that time we have at least 3 of those crappy red dots on our quality graph denoting packet loss, yet the call hasn't dropped yet. Looks like I have a lot of digging and work ahead of me to figure this one out! If you guys have any other revelations I'm all ears :)
Thanks again!

Not sure if this will help, look at this - http://doc.pfsense.org/index.php/Tuning_and_Troubleshooting_Network_Cards

Nope - I can tell you I'm on FIOS with an Intel and an Nvidia WAN and they both show same… Latency is generally about 15ms - 20ms but can real quick go to 30 or 40 or 60 if I have a ton of connections going.
Doing the same thing on a few cable setups I have up, the RRD graphs are ALL nice and even around 5. Always.

pinoyboy: Nice find. I'll have to give that a shot and see if it helps at all.
kejianshi: We do have a secondary WAN that we use just as a backup. It is a cable connection that is suppose to be 50 down / 5 up. Maybe I should see what kind of quality it has and consider moving my VoIP phones to that connection.

Yeah - It was really annoying for me because I built all the pfsense boxes and set them all up with good parts and good NICS and the one that really, in theory, is supposed to have the best connection consistently has the worse latency (as measured by pinging the gateway).
And verizon charges abit.
They do deliver the most consistent bandwidth but by far the worst latency and ugliest RRD graphs I have seen this side of Nepal or North Korea.

I forgot the follow up previously, how many phones / voip endpoints, computers, servers? And you did say this is all under the same subnet - verifying? Are computers daisy chained off the phone's switch on the back; meaning one network connection used by both computer and phone? The Cable service backup you have, is it Verizon? Lastly, to verify, is this the cloud based service of Fonality or the on premise solution?
-
We have about 20 VoIP phones, 40 machines, and 5 servers.
Yes they are all on the same subnet.
We have about 10 of the machines daisy chained to the VoIP phones.
The cable server backup we have is Time Warner. Our Fonality service is cloud based.Thanks

This means internal extension to extension calls are also routing to the cloud solution correct? Do you know how many minutes you guys average per month–regardless of before/after Fonality? What is the cost of this solution (question is due to alternative methods)? Does Fonality provide any type of vpn device direct to their network or is this straight through over the Internet (direct over the Internet is least reliable without guaranteed service allocation)? What type of network switch do you have (ALG related question, gigabit, model, QoS parameters, etc)? By the way, these are just subset of information we capture from clients experiencing these issues. You can always PM me if you do not wish to send certain info out publicly.

Yes, as I understand it, all calls whether internal or external are routed through the cloud.
We probably use about 1500 mins per month. That's a rough guess based on how many mins we were previously using between our regular calls and our conference bridge system that we now also have with Fonality. I bumped it up a little because now we have more phones then we previously did so I know a few people are making calls that weren't previously because it wasn't convenient.
The cost is roughly $15k per year for all of our phones (we have another office as well that isn't experiencing these issues but their call volume is much much lower). All total we have about 30 phones.
Currently it is just straight through the internet and as far as I know they do not offer any VPN solution. However I will call them tomorrow and ask that question.
We have 2 Netgear GS748TPS switches stacked. These are POE Gigabit switches. http://www.netgear.com/business/products/switches/stackable-smart-switches/GS748TPS.aspx
As far as QOS on the actual switch, I have not touched any of these settings.Let me know if there is any further info I can provide!
Thanks

At that price, Fonality is ABSURDLY expensive and the service is not even guaranteed by the way they deliver the lines (no QoS guaranteed over Internet). You can try and see how your other backup cable line is or you can catch up with me anytime during business hours, I sent you a PM.
