The report card
Best for SIP trunks and numbers, paid by the minute
Flowroute sells SIP trunks, numbers and texting, billed per minute and per message. It's a carrier, not a phone system, and its fees and 911 charges add to the listed rates.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Inbound from $0.005 a minute, US and Canada outbound from $0.00833, with volume quotes. That's usage billing, so it can't be set against per-seat prices. |
| Free plan and trial | F | No free plan and no free trial on record for this listing. |
| Features | D | Voice trunking, numbers, SMS and MMS, routing and fax. It needs your own phone system to be useful. |
| Ease of use | D | No store rating on record. You connect trunks to a PBX yourself. |
| Platforms and integrations | C | Web only, with no integration list on record. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Flowroute is for
- Fits if you run your own PBX and need trunks and numbers
- Works for providers who pay for what they use
Who it is not for
- Not for you if you want phones and extensions, as it's a carrier
- Watch out: texting fees and surcharges come on top of the listed per-message rates
- Pricey if you add 911, at $1.39 a number a month plus a $1.50 mandatory fee, and $95 for an unprovisioned 911 call
- Skip it if you want unlimited plans here, as the page points to SIP.US for those

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Flowroute you would be making phone numbers and calls carried over the phone network. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 76 of the 77 other business phone systems grade higher.
What you could not
- Phone numbers and calls carried over the phone network.
- Fax numbers connected to the phone network.
- Texts from a business number, registered with the carriers.
- An API that other software can build on.
What this rests on. Flowroute’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
