Solved Twilio SIP Trunk Domain already exists

[Dunblue]

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

Trunk Domain sms.pstn.twilio.com already exists





It will not proceed past this page. Have tried on more than one PBX.

This is a configuration on Twilios end. someone already has the sms.pstn.twilio.com trunk name.

Ah, thank you. I hadn't spotted the correlation between the two.
