Twilio as a SIP provider

@EddieJennings said in Twilio as a SIP provider:
@scottalanmiller No. I'm trying to go through the Altigen CDR to try to get an accurate count of non-toll free inbound minutes.
Add a couple zeros and its a pretty big deal. Just look at annual savings for example.
Inbound will be huge, 50% or more savings over voip.ms
I would use Telnyx for outbound. Way easier to configure and its .0075 with 6/6 billing on outbound. Also, when you call out to 800 numbers Twilio will charge you, Telnyx will terminate the call for free (as it should be for the calling party)
There are some other advantages with caller ID passing via Telnyx that Twilio will give you problems with if the number isn't in your DID list.

So a bit of savings there, but not massive. But not bad.
He is comparing those numbers against his Windstream bill. A number we have not see. But willbe significantly higher than those numbers.
-
Here are some numbers. Here are a few things to note. First, minutes are as accurate as I can get from my CDR cross-referencing tasks. Second, a "normal" Windstream bill is around $750. This month was the worst of the toll-fraud. Third, add about $5 / month for a Vultr instance for Twilio or Voip.ms. Fourth, savings will be event more when if cut out some DIDs, as we're not using more than 50 at the moment.
Edit: Removed incorrect figures.

damn - nearly a 75% savings.

Bah, realized I had my sum-formula written incorrect. Here's the real deal (including Vultr hosting)

Should be $6 for hosting if you use their auto backup feature also.
But yeah, those are pretty typical savings when coming from legacy systems.

A "normal" month comparison. Minutes for 60/60 would probably be more, but it seems like it's a 10% increase over 6/6 minutes. This is the best estimate I could make.
-
I did not look at your calculations, but are you calculating the inbound and outbound on the right costs since Twilio has different rates on that?
Just making sure you are doing it all right.

@JaredBusch Thanks for checking, and I have. I'll do one more check of all of my numbers before it's all presented to my bosses.

I would not show specific names and totals to them. It should be presented in terms of % saved per month or $ saved per month. With a generic "SIP Provider" noted.
Because as soon as you show specific names and numbers, you will be stuck with that no matter what you find out after more testing.

100% agree. Said spreadsheets are for my own calculations.

@EddieJennings 6/6 is about 7% savings on average, it's not as simple as the way your calcing it.
I have to apologize but Telnyx being outbound at the rights I described above is at over a million minutes per month of usage, which is the last number I paid attention to. So it's on par with voip.ms

How ought I calculate it? I took my CDR, which has the actual time of the calls and created two new columns. One column rounded up anything starting at 1 second over the minute to the next minute. The other column took the time and rounded it up to the next 1/10 of a minute. Taking a sum of each column seems like it would give me the total minutes calculated for 60/60 and the total minutes calculated 6/6, which I can then multiply by the rate for the SIP service.

That is exactly how you calculate it.

Unless @bigbear is talking about my "normal" month estimate. I don't have CDR before the toll fraud started, so I made an estimate based on the proportion of 60/60 and 6/6 minutes from my last bill.

Most likely he assumed you did not calculate as you did. Most people cannot figure it out even once explained. I cannot count how many times I have done this.
-
@EddieJennings you did it correctly then
-
Debated on making a new topic, but I figure since I enjoy playing necromancers in D&D, I'd resurrect this.
After much gnashing of teeth and the kind @JaredBusch taking the time to help verify that, in fact, you really can terminate calls with Twilio and FreePBX, I figured out the problem:
Credentials.
Bloody credentials.
To those who play with Twilio, know that the username used for trunk authentication is case-sensitive. Though, I'm still blown away that this was even a problem, as I was copying / pasting credentials with my test; however, I confirmed that calls can be terminated and verified that the username is case-sensitive. Oh well, my pride will recover, and as a result my company will probably save an additional $10 / month on SIP service.

I live in UNIX, I assume everything is case sensitive

I learned this lesson in SSIDs a few years ago - I feel your pain!
