Sendo does not currently support voice calling through our platform, but there are ways to enable voice calling on your Sendo numbers using third-party services.

​
Inbound calls

You can now enable call forwarding for your Sendo numbers to forward inbound calls to a different phone number. To do this, you can open the campaign on your dashboard and click on the “Numbers” tab. Here, you can click “Enable forwarding” next to the number(s) you want to forward calls from, and follow the prompts. Once this is done, all inbound calls to that number will immediately be forwarded to the number you specified.

If you want to use an (IVR) system or a voice API to handle inbound calling, you can use a third-party platform like Twilio to setup voice calling on a separate number, then forward your Sendo calls to your Twilio number. Please contact support if you have any questions about this forwarding process.

Coming soon: Enable call forwarding for all numbers at the campaign level.

​
Outbound calls

Some voice APIs allow you to use any phone number you own as the caller ID for outbound calls. So, to make outbound calls from your Sendo number, we recommend using a third-party platform like Twilio. To do this, you must add the number as a Verified Caller ID on the Twilio dashboard by confirming a 6-digit code (guide here). Once this process is completed, you will be able to make calls from your Sendo number using the Twilio Voice API.
