How to connect Flowroute to VICIdial

Connecting Flowroute to VICIdial means adding it as a SIP carrier that authorizes your server by IP address rather than a login. Flowroute is a wholesale voice provider that leans on IP authentication — you give them your server's public IP, they whitelist it, and no per-call password is sent. Here is the whole setup.

What to get from the Flowroute portal

Sign in to your Flowroute dashboard and gather the connection details before you touch VICIdial. You are not inventing anything here — copy the exact values Flowroute shows you.

• The SIP domain or host that Flowroute lists for your account — this is where outbound calls are sent.
• Your authorization method. For IP auth, register your server's static public IP in the portal so Flowroute accepts traffic from it.
• Any inbound numbers (DIDs) you bought, so you can route them later.

Add the carrier in VICIdial

Go to Admin → Carriers → Add New Carrier. A Carrier entry is how your dialer reaches the phone network. Give it a short Carrier ID (no spaces) and a name. In the Account Entry, paste a peer block for the SIP trunk:

• disallow=all then allow=ulaw — pins the codec so audio is predictable.
• type=friend — lets calls flow both in and out over the same peer.
• host=<the Flowroute SIP host from your portal> — for IP auth there is no register line.
• context=trunkinbound — routes inbound calls into VICIdial's DID handling.

Set Protocol to SIP. In the Dialplan Entry, strip your campaign Dial prefix (the leading 9) and add the country code Flowroute expects, dialing the digits out to your peer. Set Server IP to the Asterisk box this carrier runs on (0.0.0.0 means all servers). Finally set Active=Y.

How the call flows

  A[VICIdial Dialer] --> B[SIP Carrier Entry]

  G --> H[In-Group Agent]

Verify the trunk

On the Asterisk CLI run sip show peers. A reachable SIP peer means the trunk is up. Then place one test call from the Campaign Detail screen and confirm two-way audio with RTP flowing and that your caller ID arrives. Only point a production campaign at Flowroute once a manual test call connects cleanly.

A few things worth checking on the first call. Make sure the number you dial leaves in full E.164 form after the strip-and-prefix, since wholesale carriers reject malformed digits with a fast busy. If you hear one-way audio, the trouble is almost always RTP being blocked rather than SIP signaling — the call connects but media can't flow back. And if you plan to run high call volume, confirm with Flowroute how many concurrent calls your account allows so the dialer doesn't outrun the trunk and start getting rejections during peak pacing.

If you want the broader picture, the carrier integration guide covers every carrier field, and registration vs IP auth explains when each method wins.

VICIfast hands you a dialer with a fixed public IP in under 40 seconds, so IP-auth carriers like Flowroute whitelist you once and stay working. See pricing to get a box and bring your own carrier.
