SPLIT BY MARKET

Start from your markets, not from one carrier

didlogic operates its own network (12 physical PoPs, AS13006) and offers international routes and numbers across 140+ countries, with availability checked by market, number type, and regulatory requirement. Flowroute, a BCM One company, focuses its number services on the United States and Canada, including E911 and CNAM.

If you are starting from scratch, begin with the markets and number types you need. A system that routes by destination or number can use each carrier where it fits. They are independent services: your PBX or platform decides which calls go where.

Compare both on the routes, number types, and emergency-service requirements you actually need.

START WITH THE WORKLOAD

Which one fits your stack?

Both are carriers: they connect your SIP traffic to the phone network. Flowroute is positioned primarily for US and Canada number services, while didlogic supports international routes and numbers across its published 140+ country footprint, subject to availability.

Where didlogic is the stronger choice

Your system already routes by market, so the non-US and Canada share can go to a second carrier.
You need international routes or numbers across multiple markets.
You want outbound rates per route and operator before you sign up.
Outbound calls need CLI passthrough or caller-ID rotation.
You want a carrier that operates its own network, with 12 physical PoPs and AS13006, and an engineer answering tickets 24/7.

Where Flowroute is a good fit

Your numbers and traffic are in the US or Canada.
You need E911 or CNAM on US and Canadian numbers.
You want unlimited concurrent SIP channels on pay-as-you-go, with no monthly minimum.

WHERE TO START

Good workloads to test first

International outbound

Destinations outside the US and Canada. Compare per-route rates, call completion, and caller ID on one destination group.

Numbers outside the US

Check availability for the countries you are adding, then route inbound calls to your existing PBX or platform.

AI agents with international callers

If Vapi, Retell, LiveKit, or your own stack runs the agent, point one market’s SIP trunk at didlogic and compare the same calls.

Numbers held elsewhere

Outbound caller ID from numbers you keep with another provider. Test CLI passthrough on one route.

The didlogic network, in numbers

didlogic operates AS13006 across 12 physical PoPs, with direct Tier 1 connectivity and SIP provisioning through the portal or API. Evaluate routing and call quality using your own traffic.

CALLS PER SECOND

Check capacity before a dialer or AI workload goes live

On didlogic

CPS and concurrent channels are raised on request for the trunk that carries your test. Outbound channels are set by account level: 5, 50, or unlimited.

On Flowroute

Concurrent SIP trunk channels are unlimited at no additional cost. The pages we reviewed do not state a call-setup rate, so confirm the CPS limit for your account.

AI agents and dialers start calls in bursts. Bring your real peak CPS so both sides are tested at the rate you will actually run.

Cost model comparison: Flowroute bills US and Canada minutes and numbers at listed rates and shows international outbound rates in its Manage portal; didlogic publishes outbound rates by route and operator, bills inbound and number rental by country, and raises CPS on request.

TEST BEFORE YOU DECIDE

Test on your own traffic before you commit

Whether you are choosing your first provider or adding a second one, start with one market, route group, or AI agent. Expand only if the result justifies it.

Test didlogic

Step 1

Add a didlogic test connection

Claim a free test number once your business account is reviewed, add a test trunk, set authentication and caller ID, and agree the destinations to test.
Step 2

Route a representative sample

Use one market, one route group, one AI agent, or a controlled share of outbound traffic.
Step 3

Measure both on the same calls

Measure call completion, post-dial delay, caller-ID presentation, audio, DTMF or transfers, billing increments, and unit cost on comparable traffic.
Step 4

Expand only if it earns it

Add routes, markets, or numbers only after the technical and commercial result is clear. Porting stays a separate decision.

CUSTOMER STORY

Why an Albanian dental clinic calls its European patients on local numbers

Family Dental Care treats patients travelling from Italy, Germany and France, but calls from an Albanian number went unanswered by people who had just filled in an enquiry form. The clinic now runs local numbers in each target market through didlogic, so a prospective patient sees a domestic number and can call straight back on it.
