SIP Trunk Provider you use?

(Ecnorm) #1

Hi FPBX community! Good day. I am a newbie here. We are testing freepbx for a small office situation with need for maximum 3 lines. plus International calling, toll free inbound (U.S) - basic setup. I am evaluating different SIP trunk providers.

I would like to know who do you use for your SIP provider? We would like to keep costs low without compromising quality, so i would appreciate your feedback / suggestions on which SIP provider you use, and who do you recommend?

Thank you!!

From another post on the topic.
1st shameless plug: It auto configures in FreePBX and supports FreePBX development.

  1. Know your usage. do you need 30 minutes a month or 43,800
  2. Now math: expected usage/total cost = cost per minute. Take note of round-up (15 sec = 1 minute_
  3. Use someone trustworthy. Don’t use crazy ned’s sip outlet and gold exchange.
  4. Look for support. Do they tell you how to configure stuff or will you have to monkey with it.
  5. Just use sipstation because it supports FreePBX development :slight_smile:


In the old days, each line required a physical copper pair between you and the central office. They were expensive. With VoIP, you can be free of the ‘lines’ concept. Pay a small monthly fee per number, plus a per-minute charge for calls in and out. Customers never get a busy signal. You never have to ‘wait for a line’ to call out. You don’t need to plan for and manage seasonal variations, promotions or growth. If you like this pricing model, my first choice would be Flowroute. Other first-class (IMHO) providers offering this are Vitelity, Callcentric, Twilio. A cut below, look at Anveo,, Plivo. I’m also familiar with the down-and-dirty, but won’t discuss them unless cost is your primary concern. On Flowroute, for one toll-free and one geographic number, expect to pay ~$4/month + $0.015/min. (other than toll-free incoming) + $0.025/min. (incoming toll-free). This includes an estimate of per-minute rounding, USF charges, CNAM lookups, SOMOS dips and E911.

However, pricing based on channels (‘lines’) is also available. Some users prefer a predictable bill, even if it’s somewhat higher. Also, some providers promote this model, because it makes for easier comparison with traditional carriers. Unmetered incoming (on a local number) with three or four channels is offered by Vitelity, Callcentric, Anveo and others. With these plans, outgoing calls are still billed per-minute. There is usually a usage cap (Vitelity’s is 4000 minutes) or ToS restrictions against telemarketing, etc. Although these are an excellent value for small businesses, beware that if growth requires additional channels, you may need to go to a much more expensive plan (or change providers).

Several providers offer a flat-rate plan for both incoming and outgoing. Although these are IMO generally poor values, SIPStation is an exception because they include numerous features, some of which are unavailable elsewhere. See . There was a recent discussion of this on Broadband Reports that became quite heated; see . The last post is my attempt at presenting a balanced viewpoint. It was apparently successful, as it was upvoted by both adversaries.

My primary provider is AnveoDirect. Incoming numbers are $0.19/mo. + $0.004/min; carrier is Over the past four years, it’s been flawless except for one outage caused by a fiber cut in my Reno, NV rate center. Reno is pretty small with just one ‘carrier hotel’; any other provider would have been similarly affected. Outgoing uses their ‘smart’ routing with a limited set of carriers, averaging ~$0.005/min. for my calling pattern. Failover (less than 1% of calls) goes to Flowroute. To toll-free numbers (free on Flowroute), the order is reversed. E911 is also with Flowroute.

We may be able to give better advice. Post your approximate usage, cost expectations, countries called, etc.

@Stewart1 thank you again for writing that neutral review.
