Right. >- The sender can be spoofed. And you don't even have source ips to >check its source. No, SMS is not like VoIP. People in the phone biz tell me it is extremely hard to fake the source number in SMS. Look at any of the SMS gateway APIs and they all make you jump through hoops verifying the source number before they let you send anything. >On the other hand, email has drawbacks as well. ... Uh, yeah, we know. >I think the reason many providers use SMS reminders for appointments >(other than inertia) is because that's a lower common denominator. I think it's because an SMS is more likely to pop up an alert on your phone. Other than a handful of edge cases, everyone who can get SMS has an email address. R's, John
