Thank you for the info.  I'll await the deeper dig into this as you suggested.  Since posing this question, I have sent another SMS to 15 people and 6 of those including my own cell phone number are creating the same "rejected channel."  One number was tagged "recipient not reachable" so I hope there is a solution since nearly half to the recipients don't receive the texts.  I'm assuming that there are just still bugs to work out and I appreciate your help with this.  Thanks, Steve ...
