I am trying to create a Twilio SIP trunk to use for SMS, following the guide here https://www.3cx.com/docs/sip-trunk/twilio/

I have the account and the number set up, but the 3CX system isn't creating the trunk as it's supposed to. For the record we do not have any other Twilio's trunks, despite what the error in red suggests

How to set up the Twilio trunk properly?

Rename it to something other than just Twilio - that name is reserved.

Thank you so much.. It helped...
I suppose there was some guidance in the error note; it could have saved some frustration while creating the trunk.

The name you provide there is used to create a unique SIP URI which is used to identify your trunk when sending calls to Twilio. This needs to be unique across all Twilio trunks.
