SMS Invalid from address 40305

[waynetruck]

I have set up SMS with Telnyx it appears that all of my setting are correct based on the 3CX information when I attempt to send a message I receive:
Invalid 'from' address (40305): The 'from' address should be string containing a valid number associated with the sending messaging profile.
I am unable to receive messages

Hi @waynetruck,

Does the TEST button return a positive result?

Also, where are you seeing the error message, could you be as kind to attach a screenshot?

Yes the test passes

Hi @waynetruck,

Having a look at the error code 40305 from Telnyx seems to point to "The value must be a string containing a valid phone number in +E.164 format, a short code, or an alphanumeric sender ID associated with the sending messaging profile."
