Who it is for

For anyone who sells, buys or presents a caller ID

A caller ID that arrives intact is part of what a route is worth. CLI Check shows you whether it does, on the networks your traffic reaches.

Carriers
Check that a new supplier delivers the caller ID it sold you before traffic moves, and keep the proof when it changes.
Call centres
Make sure the number your agents present is the number customers see, so call-backs land and answer rates hold.
Switch operators
Test every supplier trunk on your Switch from one place, and send the result straight to the supplier when a route slips.

One test, the whole picture

The number you sent, the number they saw

Every test places a call over the route you choose to a handset in the destination. The number that appears on the screen is recorded next to the number you presented, with the network the handset is on.

Alongside it you get the answer check and the SIP trace of the call, so a mismatch comes with the evidence to fix it.

  • Mobile network named on every result
  • Post-dial delay and every SIP message

What it does

Caller ID testing built for carrier work

From a single check before you buy a route to every supplier tested around the clock.

  • Handsets in the destination

    Each test rings a handset on a mobile network in the country you are testing, in 70+ countries. What the screen shows is what your callers' customers would see.

  • Caller ID, network by network

    Results are recorded per mobile network, so a route that passes on one network and replaces the number on another shows up as exactly that.

  • A SIP trace on every test

    Every request and response of the test call, with timings, kept with the result. Post-dial delay and where a call failed are there to read, not to guess.

  • False answer detection

    Each answered call is checked against what the handset recorded, so a route that answers early or bills for calls that never connected is flagged.

  • Scheduled with RouteWatch

    Turn any test into a monitor that runs on the schedule you set and records every result on a timeline.

  • Alerts where you work

    Hear about a change by email, in Telegram or on a webhook into your own systems, the moment a test stops matching.

  • Reports your supplier can open

    Every result has a shareable link with the caller ID sent and shown, the network and the trace. No account needed to view it.

  • Everything over the API

    Start tests, read results and manage monitors over the REST API with the same key as the rest of your account.

How it works

Three steps to a verdict

In the dashboard or over the API, with the same account you already use.

  1. Step 1

    Choose a route and a caller ID

    Pick a supplier route on your Switch or the marketplace, or enter the SIP address of any switch. Set the number to present and the destination country.
  2. Step 2

    A handset takes the call

    The test call goes out over that route to a handset on a mobile network in the destination. The number it displays is recorded beside the one you sent.
  3. Step 3

    Read the report, share it

    Match, Partial, Replaced or Restricted, the network, the answer check and the full SIP trace. Send the report link to your supplier in one click.

Coverage

Handsets in 70+ countries

Tests run to handsets on mobile networks in the destination country, not to a lab. Before you start a test, the dashboard shows which destinations have a handset available right now.

Prices in US dollars, excluding taxes. Tests beyond the allowance are charged at the plan's extra test rate. Single caller ID tests on marketplace routes stay available without a plan.

What does a CLI Check test tell me?
Whether the caller ID you presented reached the handset intact. Each result is Match, Partial, Replaced or Restricted (withheld), with the number you sent beside the number shown, the mobile network, whether the answer was genuine, and the SIP trace of the call.
Which countries can I test?
Tests run to handsets in 70+ countries. The dashboard shows which destinations have a handset available before you start a test, so you never pay for a test that cannot run.
Can I test routes that are not on PacketExchange?
Yes. Test any supplier route on your Switch, any marketplace route before you buy it, or the SIP address of a switch we do not host, as long as it accepts calls from our addresses.
What is false answer detection?
A false answer is a call your supplier reports as answered when it never reached the person called, often to bill for time that did not happen. CLI Check compares the answer the route signalled with what the handset recorded and flags the difference.
How do I show the result to my supplier?
Every test has a shareable report link with the caller ID sent and shown, the network, the answer check and the SIP trace. Your supplier can open it without an account.
What happens if I use all my tests?
Extra tests are charged per test at your plan's rate, from $0.18 on the largest plan. You can move to a bigger plan at any time from the dashboard.
How do alerts work?
Choose email, Telegram or a webhook for each monitor. You are told when a test stops matching, when a false answer is detected, and when the route recovers.
Is a plan cheaper than single tests?
Yes. A single caller ID test is $0.25 pay as you go. Plans bring that down to $0.16 a test, and extra tests beyond the plan still cost less than pay as you go. The bigger the plan, the less each test costs.
Is there a contract?
No. Plans are monthly and you can cancel or change plan from the dashboard at any time.
