Hi, I'm getting this response from the service

If I use extension 101, I can't log in with my account (since it's 102) but when I log in with 102 I get this weird thing.

This is sandbox.

Note that when you are using your sandbox for testing, you have to use the sandbox phone number and extension - you cannot use any of your live phone numbers or extensions.

This is not applied to sending SMS message. It needs a direct number or a digital line. Main company number should be SMS provisioned too and can be used with the extension it's associated with (via IVR setting).
