CallPalConnect Flowroute to CallPal
Fund a Flowroute account, buy a US number and register CallPal with your Flowroute SIP credentials — about fifteen minutes once the account can call.
Before you start
- A CallPal account. The 14-day trial is enough — no card required.
- In CallPal, permission to manage SIP trunks. Owners and admins have it by default.
- A payment method and $40 for Flowroute’s first deposit. Flowroute is prepaid and the deposit becomes calling credit. Flowroute bills your minutes, CallPal does not.
- A US or Canadian number to call from. Flowroute only accepts a caller ID that is a real, in-service, local North American number — not toll-free.
Open a Flowroute account and add credit
Sign up at manage.flowroute.com/signup, add a payment method, then add at least $40 of credit — the minimum for a new account.
Flowroute may ask a new account for identity documents before it can call. If the portal shows Additional Information Needed, email Flowroute support; they send a link to upload an ID and proof of address.
Buy the number your calls will come from
Go to DIDS → Purchase, filter by area code and press Purchase beside a number. Answer No to messaging if you only need calls.
A number bought from Flowroute on the same account is what carriers trust most, so your calls are less likely to show as spam.
Copy your SIP credentials
Open Interconnections → Registration. It shows your 8-digit Tech Prefix and your SIP password — the username and password CallPal registers with. Keep this page open for the next step.
The same page lists Flowroute’s servers (its points of presence). CallPal uses the US East one by default; pick the one nearest your team if that is not the East Coast.
us-east-va.sip.flowroute.com
Add the trunk in CallPal
In CallPal, open Settings → SIP Trunks and press Add Trunk. Give it a Name you will recognise in the call log — "Flowroute" is usually the right one.
Pick Flowroute as the Provider template. It fills in the SIP server host,
us-east-va.sip.flowroute.com, and the port for you, and selects Credentials (register) as the authentication method.Enter the Tech Prefix as the Username and paste the SIP password. Your password is written to a secrets manager, never to the trunk record.
Add your number as the caller ID
Under Phone numbers (DIDs), enter the number from step 2 in E.164 format — a plus sign, the country code, then the number. Calls placed through this trunk present it.
Flowroute rejects a caller ID that is not a real, in-service, local North American number, and toll-free numbers are refused. Use the number you bought in step 2.

Test the trunk, then activate it
A trunk you have just added reads Pending, with Health Unknown. That is expected, not a fault.
Press Test to probe Flowroute immediately. When the probe succeeds, Health reports Up. Then press Activate to enable the trunk — Status moves to Active straight away and your team can call.
If Status settles on Failed or Health reads Down, the Tech Prefix or the password is wrong. Interconnections → Status in the Flowroute portal shows whether CallPal registered.
What you configure
- Provider template
- Flowroute. Fills in the host, port and audio settings for Flowroute’s registration; you can still change any of them.
- SIP server host
- us-east-va.sip.flowroute.com, filled in by the template. Swap in another Flowroute server from Interconnections → Registration if one is nearer your team.
- Authentication method
- Credentials (register), selected by the template. CallPal signs in to Flowroute with your Tech Prefix and SIP password.
- Username and Password
- Your 8-digit Tech Prefix and the SIP password from Interconnections → Registration. The password is stored in a secrets manager, not on the trunk record.
- Phone numbers (DIDs)
- The Flowroute number your calls present as caller ID, in E.164 format. It must be a local North American number, not toll-free.
What it does not do
Worth reading before you roll this out to a team — some of these are how CallPal works, others are the carrier’s own rules.
- CallPal is outbound only. No inbound routing, no IVR, no predictive dialing.
- You pay Flowroute directly for numbers and minutes, at Flowroute’s rate. CallPal does not resell phone service, so nothing about calling cost passes through your CallPal plan.
- The caller ID must be a real, in-service, local US or Canadian number. Toll-free numbers are not accepted as a caller ID.
- A new Flowroute account blocks any call that costs more than $0.01 a minute, which rules out most international destinations. Raise the Maximum Outbound Rate, or allow specific countries, under Preferences → Fraud Control in Flowroute, not in CallPal.
- CallPal connects to Flowroute by registration only. Flowroute’s IP-authenticated mode needs its tech prefix on every dialled number, which CallPal does not add.
Questions
What does calling cost?
Whatever Flowroute charges you — there is no CallPal markup, because CallPal never bills minutes. You add credit to Flowroute and calls draw from that balance; your CallPal plan is the same however much you dial.
Calls to other countries are blocked.
Make sure a call within the US works first. Then open Preferences → Fraud Control in the Flowroute portal: the Maximum Outbound Rate starts at $0.01 a minute, which blocks most international destinations. Raise it, or add the countries you call to the Destination Whitelist.
The trunk tests fine but calls do not connect.
Check your Flowroute balance, and check that the caller ID in CallPal is the number you bought from Flowroute. Flowroute rejects calls from a caller ID that is not a real, in-service, local North American number.
Can I call from a toll-free number?
No. Flowroute needs a local North American number as the caller ID.
Can I add a second carrier for failover?
Yes. Add it as a second trunk in CallPal. If the first stops registering, calls move to the next healthy one.
