Solved Outbound SMS on Bandwidth trunk not sending

[SaraMarlar]

I have a version 20.0 Update 1 (Built 673)
3CX PRO 4 SC

We have successfully vetted a new 10DLC brand and campaign with Bandwidth
I've assigned our DID to the campaign, enabled SMS on the sub-account on the trunk side
I've created the application and entered the Webhook URL from 3CX in the Callback URL section in the application in Bandwidth.
I've assigned the DID to a user in 3CX
I've enabled SMS in the SIP trunk settings in 3CX and added the account info required as directed by Step 3: https://www.3cx.com/docs/sip-trunk/bandwidth-usa/

All outbound SMS fail, but inbound SMS is perfectly fine:

The error is from the provider side. This needs to be checked from their side.

Even though inbound SMS works fine?

This issue has been resolved

In order to resolve I had to create an API token and use the token and secret key in place of user credentials in the SIP trunk settings in the PBX.
