I've been searching for a few hours on the best way to add sms notifications and reception to my PHP website. It seems that it's easy to send texts (to an email forward to a phone), but hard to receive them without an SMS gateway. Clickatell was recommended a lot.
But: I stumbled across a few article recommending Google Voice as a channel to send and receive SMS. (Here's one post: http://sudocode.net/article/190/receiving-incoming-smstext-messages-from-google-voice-in-php/)
Is there any reason I shouldn't/can't use a Google Voice number (and PHP) to handle my sms outbound and inbound messages?
