Answersbefore a ticket

How to connect, route, bill and settle on PacketExchange, answered in plain terms. Cannot find it here? Open a ticket and we reply by email.

01 / Connect

Get traffic flowing

Accounts, credentials, trunks and the first call.

How do I connect, and where do the trunk details come from?

SIP trunks for voice, SMPP binds or the REST API for SMS. Credentials are issued the moment you buy a route and are live on our edge within a minute.

SIP auth
IP whitelist, or username and password (digest, no REGISTER needed).
SMS
An SMPP bind, or POST /comms/sms with an API key.
Codecs
G.711 and G.729.

How fast can I go live?

Minutes. Open an account, take your API key, top up, and send your first call or SMS. No sales call, no contract.

Smallest top-up
$5 by card or crypto, $100 by wire.
Try it first
Test keys run a request through routing and pricing without delivering anything. An invite code can add up to $50 of test credit.

Do I have to buy a route before I can make calls?

No. You need termination, and it can come from the marketplace or from a carrier you contract yourself.

From the marketplace
Buy a listed route and send over it.
From your own carrier
List them as a private route on your own account and send over it directly. No purchase involved.
Who can see a private route
Only you, plus anyone you choose to share it with. It never appears on the public marketplace.
How we pick one
Your own routes and your purchases are treated exactly the same when we choose a route for a call.

Does a caller ID have to be a number I bought from you?

No. Any valid E.164 caller ID is accepted by default, so you can build and test the call path before buying a single number.

Buying US voice routes
Needs a completed STIR/SHAKEN compliance profile, and the purchase is reviewed before it goes live.
Restricted trunks
A Switch operator can limit which caller IDs a trunk may present.
What carriers do
They may reject caller IDs they do not recognise, so a real, reachable number performs better than an invented one.
What buying numbers is for
Giving each customer an identity and somewhere to receive calls. Not permission to dial out.

Can I send one-time codes by voice call as well as SMS?

Yes. The Verify API creates the code, sends it by text or by a call that reads the digits aloud, and checks what the user types. Only a hash of the code is stored.

Endpoints
POST /verify/start · POST /verify/check
Voice languages
English, Spanish, French, German, Portuguese and Hindi.

What delivery status do I get for an SMS?

The send-time result first: accepted by the route, or failed with the reason. Where the route returns a carrier delivery receipt, the message then moves to delivered or failed (a failed message is refunded); on routes that return none it stays sent. GET /comms/sms/{id} shows the timeline.

Which numbers can send and receive SMS?

The number catalogue does not flag SMS support per number yet. If you need a number for texting, ask support before you buy.

What upstream tells us
The number type only, such as Local, National, Mobile or Toll-free.
Why we do not infer it
A guess could have you buy a number that cannot text.
When it changes
Per-number SMS capability will appear in the catalogue rather than being inferred.
02 / Route

Choose where traffic goes

Which route carries a call, and whose carrier is behind it.

Is a problem on your side or mine?

Check the status page first. Every service, from voice termination and SMS to the API and payments, is probed each minute and published with 90 days of history and any open incident.

Get told
Subscribe on the status page for an email when an incident opens, changes or resolves.

How is route quality shown?

Every route lists the ASR, ACD and PDD its seller states, next to our Exchange Score: a 1-100 rating we calculate from those stated figures and the route's tier once it has carried traffic, so you can weigh quality as well as price.

I have my own carrier. Do I list it, or just use it?

Either, and you can do both. Same carrier, two jobs.

As a marketplace route
Listed for sale. Other buyers can purchase it, so other people’s traffic earns you money.
As a private supplier
Added on your Switch. Only your own traffic goes to it, and it just carries yours.
Who sees a supplier
Nobody. Adding a carrier as a supplier does not expose it to anyone.

I am selling a route. Which IPs do I allow on my switch?

Every call to you comes from PacketExchange, never from the buyer, so you allow our addresses once and every buyer can reach you. Allow all of them, for signalling and for media.

Where to find them
On the Endpoint step when you list a route, on every route’s page, and under Our IPs on My routes. We also email them the first time a listing on a new endpoint goes public.
Check it worked
Test my endpoint, on the same screens, sends a real test call from every address and says whether your switch answered, did not answer, or refused us.
Selling SMS
Your SMS platform allows one address instead. It is on the Endpoint step of an SMS listing, with a bind test for SMPP.
Not the buyer address
Buyers point their trunks at a different address. Never enter ours as your own endpoint: that field is your switch.

Allow our IPs on your switch

Every call reaches you from PacketExchange, never from the buyer. Allow all of these addresses, for signalling and for media.

Addresses
  • 144.76.120.84
  • 138.201.81.168
SIP signalling
UDP and TCP 5060
RTP media
UDP 16384-32768 from the same addresses

Calls are shared across the addresses, so allowing only one makes about half of them fail.

03 / Bill

What it costs, what you charge

Our price to you, and your price to your own users.

Do developers pay more than carriers?

No. Both draw from the same wholesale market at the same rates. The platform fee depends on how traffic reaches us, not on who you are.

Via the API or Dialer
2% of the route rate, capped at $0.001.
Over your own SIP trunk
0.5% of the route rate, capped at $0.001.

Can I bring my own app and bill my users through you?

Yes. Create sub-accounts for your users and set your own retail price above the wholesale rate.

Every call or message
Bills the sub-account at retail.
Your margin
Credited to you automatically.
Your users
Never see our rates.

Two operational questions come with sub-accounts: how a call is attributed to a customer, and where its SIP password comes from. Both are in troubleshooting.

04 / Settle

Money in, money out

Balances, CDRs and margin, on both sides of the book.

Can I sell and buy at the same time?

Yes. Most operators do both: buying termination for their own app on one destination while selling their own routes on another.

Tracked separately
Balances, CDRs and margin, for each side.
Not duplicated
The same account does both, without a second login.

Prepaid balances, platform fees and settlement on delivery are set out in developer pricing.
