How to Enable Call Forwarding

Call Forwarding is a setting on your numbers, which when activated can allow you to always call forward to a particular number you want to set or only forward on cases where there are failures establishing a call to the SIP Connection associated to the number.

1. On the number you want to have call forwarding enabled, click on the handset icon under the services column.

How to disable or deactivate call forwarding

Go back into the voice settings of the number, simply toggle off the forwarding setting and save changes. Your forwarding will now be disabled on the number.

Notes

Call forwarding from a Telnyx number to another Telnyx number is always considered off-net and will be charged according to your rate deck which can be downloaded from your outbound voice profile settings. This is due to forwarded calls being sent outbound to the PSTN.

Call forwarding is not possible to enable on numbers that are assigned to voice or fax applications, only SIP Connections. If you run into any errors when you are using the automatic forwarding via the portal then you need to set the SIP Connection Id for the number you are forwarding from to EMPTY before you start forwarding. If you need to keep the number assigned to a Call Control or TeXML application then you must forward programmatically. TeXML is the easiest following these instructions and you can substitute <SIP> for <NUMBER>. For Call Control or Voice API you can use the answer and transfer commands to achieve forwarding.
