Bring your own carriers to SignalWire

Enhance SignalWire in seconds with our powerful, cloud-based inbound and outbound call technology that seamlessly integrates with your voice API—with little or no dev lift.

Inbound & Outbound Voice

SignalWire can be easily enhanced with a minimum of development lift to augment your inbound and outbound voice with Commio's Bring Your Own Carrier (BYOC) solution.

After following these directions, inbound voice calls to your Commio phone numbers will route to SignalWire, and outbound calls initiated from SignalWire will route through your Commio outbound voice profile. Following these steps will also eliminate the need for hardcoding a SIP URI to route outbound calls initiated from your application to Commio, meaning no changes will be needed inside your application.

To start, open both your your SignalWire and accounts in two browser tabs. We'll move between both portals throughout these instructions.

Set Up SignalWire for Commio

In Signalwire, click SIP > SIP Settings. Leave default settings in place, then Save.

Create an Inbound Routing Profile at Commio

In > Inbound > Routing Profiles > Inbound Profiles

Click to Add a new profile, and in the pop-up, configure the name to be SignalWire-YourCompanyName or just SignalWire.

You may want to create multiple SIP Domains on SignalWire for different applications, which would allow you to create additional routing profiles. Be sure your naming system is descriptive so you recognize what it matches within SignalWire.

Select “DNS A” for Type and enter the full SignalWire App URL from above. Leave the sip: prefix off of the URI, it should just be the full URL.

Making Outbound Calls via the LaML API

In SignalWire, this method supports a long list of parameters. The relevant parameters for your SIP calls are SipAuthUsername and SipAuthPassword. The URL would support the same structure and SIP options as the LaML version.

A full example:
Require 'signalwire/sdk'
client = 'your-project', 'your-token', signalwire_space_url: ""
call = client.calls.create(url: '', to: ‘;transport=udp?header1=foo&header2=bar', from: '+15559988777', sip_auth_username: 'user', sip_auth_password: 'pass')

Congratulations! Inbound voice calls to your Commio numbers will now route to SignalWire, and outbound calls initiated FROM SignalWire will route through Commio.
